okay, fucking autokill? You just broke two big rules in being a good roleplayer. I'm making a vote to IC punish his character now.
Really should read the CS of the guy before you go throwing fists at him willy fucking nilly.
I'm voting definite "No" on punishing him, since you're acting too irrationally and angrily to make sound decisions.
On top of this, you nosold it anyways. Autokill isn't a thing when your character can "come back from paste" anyways. In fact, you're practically obligated to take horrendous injuries all the time, like Deadpool, Wolverine, and a host of similar characters do on a regular basis. Deadpool gets shot in the head for comedic reasons on a regular basis. You'd know that if you'd read the comics.
