Blowing away Nina after she was arrested in season three definitely counts.
Nina was Evil with a capital E, but she was cornered and only going back to jail.
The OP said heroic characters.
Jack cut off that dude’s head at the start of season 2 as well.
How about President Bartlett? He had what’s-his-name killed at the end of season 3.
Captain Janeway of* Voyager*. She killed the character Tuvix who was created by the merger of Neelix and Tuvok in a transporter accident by having him separated into his components.
Arguably B’Elanna Torres in Voyager when she breaks the robot she’s just created for a race of robots who need her skills to make more of themselves. Arguable because it’s uncertain if they qualify as people; and even more arguable if that particular robot was.
Captain Picard ( although it was in one of the movies ) killed a Starfleet officer who’d been infected by the Borg rather than letting the assimilation process finish.
What did Micheal Westin from Burn Notice do?
Personally, if I was the random peace officer of wherever Mrs Fletcher was showing up, the first thing I would do is run her out of town or arrest her and put her in the jail … someone always turns up dead…
I’m pretty sure you have to discount Janeway. As Grumman pointed out above, the OP specifies heroic characters, and Voyager only makes sense if you assume that Kate was a deep cover Cardassian operative.
Oh, no one cares. Next you’ll be arguing that the HoloDoc should be allowed to turn himself on and off.
I think that was justifable. Certainly there was no malice; he wasn’t doing it to punish the Borg but to save the officer from a horrible fate.
Spoilers for Season 8 (comics)Warren didn’t really die, Amy the [del]bitch[/del] witch somehow saved him :rolleyes:
You can say it’s non-canon, but considering these were done by Joss himself, not just some writer the comic company hired to write a licensed comic…
Anyway, I nominate Bill from True Blood. Not for all the people he must have eaten over the years, but for Sookie’s uncle. That was murder, no two ways about it.
There was an episode of Star Trek TNG where Data had been captured by a collector. It was pointed out several times that Data was programmed not to kill, but at the end of the episode it was revealed that he had fired his phaser, which had been set to kill.
Even worse, that collector was clearly just a future Warehouse 13 agent, trying to keep things out of the wrong hands!
Nah, it’s canon I guess. But this means that the First (S7 badguy for those not Wise In The Ways Of Buffy) can impersonate living people, which wasn’t the case back in S7.
Well if you’ve got a better way to stop killbots, then I’d like to hear it.
Well, given Andrew’ fairly clearly expressed orienttion, that might just have been punishment…
(You may recall him sighing over Scott Bakula.)
On an old issue of Hill Street Blues, a thug was out after Furillo’s wife. Two officers, Neal and his assholish white partner, followed the guy around all day, breaking up a couple of deals and forcing him into cold turkey conditions. He finally ran amok and they blew him away. I would say that counts.
Not to mention the fact that he was entirely uninterested in watching the wondrous Willow make out with her girlfriend. Of course, given that said girlfriend was an irritating skank whom Rosenberg became involved with only on the rebound and who was not worthy to lick the dirt off Tara’s spats, his uninterest may be forgiven.
Yeah, I was just speaking from my POV. 
Even though the situation would be more along the lines of “They’re all hot… and under eighteen? WHY, GOD, WHY???”
Don’t forget the scene where the Nerd Cameras catch Anya and Spike doin’ the nasty and Andrews comment was “He’s so cool… uh, and the girl’s hot too!”
We see him kill at least two people on screen. One was going to be killed anyway, but the other was threatening to kill Fiona.
He has also killed a lot of bad guys indirectly.
Yeah, but since Iyari Limon played peek-a-boo with my little girl some years ago at a Cleveland Vulkon, I’ve forgiven her for the travesty that was Kennedy and properly placed the blame on Joss.
Oh, I have nothing against Ms. Limon; I didn’t even know her name till you posted it. I would even say that she was cuter than Amber Benson. But I was speaking of the characters, not the actresses; I liked Tara and despised she-who-shall-not-be-named.
However, his appearance in ANGEL with his lady entourage suggests that Andrew may have expanded his range a tad.
(One day, my mom walked in when I was expanding my range a tad. I was pretty embarrassed.)
