If you could take revenge without any chance of recourse, would you? (Just a hypothetical!)
A) Yes! 
B) No. 
Hell yes!!!
Can I do it twice? :D:D
You can vote twice! 
No more to the hypothetical and no option “it depends?” I can’t vote. Sometimes the answer is “Hell YES”, sometimes the answer is “No, not worth it.”
Revenge for what?
I have lived my life such that no one has been able to earn revenge. Except for the bitch from New Jersey, but after 35 years I can forgive her.
No.
Unattributed revenge doesn’t, by itself, really serve any of my goals.
Widely attributed revenge might serve goals indirectly (“Do NOT fuck with him.”) but that opens the door wide to there being recourse.
Yes, but only after singing about it first. This goes to show that for me everything gets back to the blues and opera.
Yes I would and yes I have.
I went yes but I would have preferred a “maybe” or “depends”
If its something important enough to warrant revenge. Even in perfect safety I’m not going to bother with something piddling. And heck, if its big enough I don’t even care about recourse. Like I’ve told some people IRL ------ I’m 60 with no kids and a bum ticker; what’s a life sentence mean to me? Five years? I’m betting I could do a nickle if I had to.
My wife says I can’t and she’s been right so far.
How about “I won’t personally take revenge, but I will delight in my enemy’s misfortune”?
^ Boy, those Germans have a word for everything!
No. I don’t need to prolong the agony… on either party’s part. Just let it go, brother.
Never. Ever. I’ve seen what revenge does. Really does.
Never, ever.
I don’t think so. Depends on how you frame it, though. I’d want a right of reply that would be listened to no matter how ranty and aggressive it may get.
I voted “Yes” but only in one specific case. In that case, I would make the Spanish Inquisition look unimaginative and dull.
I clicked NO before I even read the OP. I cannot envision a situation in which I wound take revenge. AKA (nowadays) “Closure”.
Chuchill said “Revenge is a dish best served cold.” But by the,n the inspiration also cools.
I don’t see the point of revenge. Bringing someone to justice, yes. Preventing someone from causing more harm, absolutely. But revenge? That’s just selfishness.
Yes I would, and I have when able. Destroying someone’s life or finances after they’ve harmed you, and watching their growing despair is one of the best feelings possible.
To be clear, this is only for those who’ve actively tried to harm or steal from us.
After being hit by a drunk driver, we started a multi-year legal process eventually resulting in his wife leaving him, his landlord evicting him, and him losing his job. According to my lawyers, his last known location was a homeless camp under one of the city’s bridges. And later that week I got the immense pleasure of sitting by my fire, watching the sleet and snow come down, and knowing the subhuman guttermuck that tried to kill my family was shivering (and hopefully dying) outside while I sipped expensive whiskey.
Back in our yondering years, we tended to rent fairly cheap digs at each contracting location. Occasionally this got hilarious when a strutting little Napoleon landlord assumed we were poor like the rest of his renters and he could screw us over (we were 2%-ers at time).
In one case the pinhead landlord burst into the house while I was gone and my wife was nursing our newborn. When she objected, he declared he could enter anytime, and barged in with a prospective buyer for the house. I’ll skip the details but when it was all over, he lost the house to foreclosure. I wanted to buy it just to put an extra FU on the deal, but my wife talked me out of it.
In another case, the landlord tried to screw me out of my deposit. This one was too stupid to read their own rental agreement. After facing the lawsuit and discovering just how screwed he was, he actually starting crying. (This was ridiculous accusations of substantial damage to cover the fact he’d spent our deposit – not a minor disagreement over cleaning)
So the OP; Hell yeah. If someone harms me and I can (legally) get back at them, I’ll spend substantial effort and time to return the favor. And enjoy every minute of it. 
The best revenge is living well.
