"He would have", "He never would have", "I'm sure he would have been..."
All of those are just assumptions, and that's not how justice works. And...how exactly would Warren have been capable of escaping from prison? He goes to prison for first-degree murder in California, he's there for life, without parole. Where is the necessity for killing him? There isn't one.
It's how justice works in the show.
Buffy slays any and all vampires, there are some romantic leads that run counter to that, but apart from them, any and all vampires are allowed to be killed at any time.
A newly raised vampire who hasn't killed yet is slayable becasue of what they are going to do.
Of course I'm assuming Warren is going to do more, but I'm also right, Warren proved that for me when he came back in season 8, he would always keep coming back.
So...justification for killing people now is "well, they probably have a plan in place for the police, so we should just axe them"? Hmm. Yeah. I don't agree with that.
Buffy sees Warren shoot her. It would take a complete idiot not to convict him of that crime. There's a dead body and a gunshot victim. Police don't just let that go.
Buffy also has a history of violence, and a record of getting kicked out of school and being involved in a homicide case, possibly reported as a runaway, a sleezy lawyer can turn things around on her and make her look like an unrealiable witness.
Then she's gonna go into court and say Waren shot her... she probably can't as she was healed magically, it's very possibly Willows magic may have made that wound undetectable, and who knows what the doctors remember from what Willow did to them, even if they did remember they are not going to able to explain it.
That leaves Warren as shooting Tara, I think he can get rid of the gun no problem, he has no history with Tara, no motive, no evidence he was there other then a teen delinquent and her friend, you seem to just look at it as a court system as it is in real life, ignoring all the mystical elements that would be involved in the case ON THE SHOW.
"The dudes a loser" is irrelevant. There are plenty of losers in real life. That doesn't give you or I the right to kill who we please.
No it doesn't, but it makes his death more satisfying when it happens on TV.
Well, you are ignoring the radically altered set of circumstances that the man had been skinned, and only survived because of a totally unpredictable event of Amy coming to his rescue (which, as a sidebar, I find so stupid. The First appears as Warren in S7. Why is it able to do that if he's actually alive? I know he's alive, it's just another example of ignoring continuity that drives me nuts).
And this point...again...ignores the fact that Warren would have been incarcerated for life.
I don't know why people are getting so stuck up on this. Killing people because you feel like it is dead wrong. "Because they deserve it" is NOT a good enough reason. And every one of the arguments I've read here about how he remained an active threat are just ridiculous, and just read as an attempt to justify a character you guys like.
I couldn't disagree more, as far as I'm concerned it's fact that Warren would come back.
When his girlfriend dumped him, he came back and got his revenge by raping and murdering her.
When Buffy stopped his plan to rob the bank, he came back and shot her.
When Willow killed him, he came back and lobotomised her.
Still not content to bugged off, he helps to create a bomb to blow up Buffy and her girls, killing a lot of them.
Then at the last minuet him and Amy switch sides before doing a runner, where Amy suggests they go back and help the scoobies, which Warren flat out denies to do as Buffy and Willow are the enemy.
Even when he gets away they are still his enemy, to think that he wouldn't come back is delusional.
