CSM from The X-Files. He assassinated JFK, and framed Lee Harvey Oswald, assassinated Martin Luther King Jr, arranged the Anita Hill controversy and the Rodney King trial. He also ordered that the Buffalo Bills not win the Super Bowl and he drugged a Soviet goalkeeper to ensure the outcome of the “Miracle on Ice” hockey match.
According to Frohike anyway. 
Other worthy candidates:
Kripke from “The Big Bang Theory”. A rotten human.
And from the dark ages of TV, Hamilton Burger, the D.A. on “Perry Mason”, whose habitual facial expression was a sneer.
Oh, yes. He’s high on my list, too!
When faced with a minor situation, Todd’s first and ultimately only ( as he never takes time to reflect ) choice is to kill. He shows that he has zero sense of morality ( unlike Walter) and the life of crime is all that he knows or cares about. This makes him far more despicable. We are shown no other sides of him except psychopathic killer.
For Todd, capricious killing is just business and that’s the despicable part. For him, everything is about business and he kills accordingly again, unlike Walt. He flippantly kills children, not so with Walt.
This isn’t a Walt defense only that Todd is worse. Also, the selling drug thing isn’t a Walt thing as Todd was involved with the meth trade before and after Walt. They both hold that in common.
As for the Mike thing I don’t believe that’s why he killed him at all. It was not good enough that Mike disappear. He has the feds after him. Catch him and he may talk to save his granddaughter and Mike legitimately has the goods to sink Walt. He was a loose end and one that by his refusal to go along with Walt made him untrustworthy. As a crime lord, that death had to happen. No one leaves their biggest vulnerability who is defying them floating in the wind.
Right show, wrong character. Dennis Franz had a guest role in one of the first couple of seasons as a dirty cop, he was awful, but finally received his just desserts.
If you’re familiar with “Squidbillies”, it’s a tossup between:
Todd is a bad person. However he is never shown relishing or celebrating either of his murders. There is nothing sadistic about him - at least nothing actually broadcast on the show.
After killing motorcycle boy he saves the tarantula in a jar which is ambiguous. It could be a serial killer’s trophy but it could be him accepting the responsibility of taking care of the helpless collateral victim of his actions.
Right before Todd kills Andrea he says something like ‘Just so you know this isn’t personal’ which is kind of regretful. It suggests there is a deep buried morality in him.
As for seeing the other side of Todd there isn’t much but it is there. He makes no attempt to retaliate when Jessie punches him for killing motorcycle boy. Later he twice saves Jessie from being killed by his uncle’s gang (on both occasions because he feels Jessie is more valuable alive.) Todd is a polite, attentive student to Walter. Plus he is loyal to Walter. His uncle’s gang give Walter a barrel of money (and presumably don’t simply kill Walter) because of Todd.
It is a bit soppy, juvenile infatuation, but Todd clearly cares for and is protective to Lydia. He gently leads her by the hand through the dead drug gang in the desert after she chooses to close her eyes. Although he apparently tortures Jessie (not shown) he is portrayed as gently protective when he takes Jessie from the underground cage.
From recollection Todd was introduced as merely being part of a team of burglars who work under the cover of being pest fumigators. His links to the white supremacist gang came later and seemed forced by the writers. Clean, neat, non-tattooed Todd doesn’t seem to be an obvious gang member. However if we assume Todd was raised by ultra-violent criminals would that upbringing not justify a certain callousness and casual immorality in him?
Walter with his far more conventional upbringing should have a much sturdier adherence to morality and it is his betrayal of decency which is the more disgusting. Todd quite probably knows no better. Walt doesn’t have that excuse, he absolutely knows what he is doing is wrong. Plus Walter endangers his innocent family and friends. Todd’s family and friends appear to be criminals.

This is basically exactly backwards. Todd doesn’t do morality. All he knows is surface politeness.
Morton Downey Jr.
Or anyone played by Lisa Kudrow. 
Regarding Todd Alquist on Breaking Bad, I recall him bringing some ice cream to Jessie when Jessie was being held in the pit/cage. Todd was a bad person for sure but his unnecessary kind gesture of bringing the ice cream seemed to be his way of saying “Hey, I know we’re holding you in a cage and we beat and tortured you but we are both in the meth game and we are criminals and killers. This is just part of the game. I don’t want to be a total dick about it.”
Not defending him but I don’t think he was a sociopath.
As I’ve said before, Todd is a very nice young man. When he’s not out murdering and torturing, he’s probably busy helping old ladies cross the street.
What he doesn’t have is feelings. Todd can murder and torture and never, ever lose any sleep over it. Bringing Jesse the ice cream is vintage Todd. He only knows kindness in the form of empty gesture. He doesn’t do empathy.
Well… considering he had the choice of working for the Shadows, or having his brain reconfigured to be the main computer of a starship, it’s kinda hard to fault him.
Yes!
Or Janice.
Ted Bundy worked as a suicide prevention counselor, was he not a sociopath?
There is little equivalency between the behaviour of the real life Ted Bundy and the behaviour we see of Todd on Breaking Bad.
Bundy enjoyed torture, rape, murder and desecration of his victim’s corpses. Bundy would set out and actively seek victims because of the direct pleasure he attained from his acts of depraved brutality.
Todd, as far as is portrayed during his limited screen time, only committed such crimes as gave a wider, practical benefit. He was not portrayed as taking any pleasure from what he did. He was clinical and his actions were professional. Even if his poor decision making in the case of motorcycle boy was amateur.
Todd is a bad person but, as portrayed, is no Ted Bundy. The original point I made in this thread was that Todd is nowhere near as bad as Walter. Walter, for all his hand wringing and heart wrenching ‘crisis of conscience’ nevertheless continued pursuing his life of crime. Continually escalating his level of criminality generating an ever increasing number of victims.
In the end Walter even admitted that he had continued the life of crime, far beyond any perceived economic need (and there was never any actual economic need because his former Grey Matter colleagues had offered to pay for all his treatment) simply because he enjoyed it. It made him feel alive, made him feel good. Walter actually admits, on the show, he relished his time as a drug lord.
Todd could be a truly evil person although that isn’t made clear and he could equally just be painfully shy and too eager to please those around him - a situation made tragic when his family and friends, as portrayed, are all violent criminals themselves.
Walter, however, knows exactly that what he is doing is wrong. He knows people are dying all around him. He knows he is putting innocent people including his beloved family at risk but for all the crocodile tears and insincere remorse he keeps going.
Todd does evil things but shows little understanding of the concept. Todd is trying to survive. Walter is doing evil things, knows it is wrong and keeps doing it because it’s fun. It’s just a game.

When Todd’s uncle and his gang are in the desert killing Hank. When the shooting stops Todd persuades his uncle to give Walter a barrel of money. That seems pretty altruistic of Todd. Especially since there is zero likelihood of Walter ever cooking for the Nazis again so it would have been cheaper and easier to put a bullet in Walter. (I must confess that I suspect, in any sort of reality, Uncle would have ignored Todd.)
It seems that when Todd does bad things he is perceived as evil - which is fair enough. But on the rare occasions he does something that shows a trace of kindness it is simply dismissed as an empty gesture.
TCMF-2L
Yeah, but they’re just traces. They’re drops in the bucket compared to the evil he does. They fall flat, because there’s so little heart there. It just makes him more scary. When Todd gives Jesse ice cream, that sends a shiver down my spine, because if Todd really thinks that it somehow makes up for the torturing and murdering, his moral compass is so out of whack that he might as well be living in the Bermuda Triangle.
If a murderer who has proper emotions wants to murder you, you can at least plead for your life, and appeal to the goodness in his heart. Maybe he’ll kill you anyway, if he’s angry or sadistic enough. With Todd, you’ll be SOL either way, because even if you succeed to appeal to his kindness, he’ll just say “it’s nothing personal”, and shoot you anyway. That’s where kindness ends for him. He thinks that he has kindness covered as long as he’s being polite.
Hey, this is fun. Aren’t BB characters great? I mean, we could do this all day, and it never gets boring. Should we hijack this tread, or get a room?
In a show that features absurdly brutal slavery(who kills valuable slaves?), parents that hire soldiers to rape their own son by proxy, people that rape and murder for kicks, and a guy that enjoys hunting women like animals and then skinning them alive, the worst person is a mentally disabled dude that kills bugs?
By “television character” can we include pro wrestlers, specifically their on-screen gimmicks? Because if so, the list is LONG, with Mr. McMahon (the on-screen persona of Vince McMahon) probably at or near the top.
