No. I'd feel terrible. The death of someone doesn't only affect them, it affects them and everyone of the victim's friends, family, spouse, etc.
No consequences...Meaning his friends and family wouldn't give a stuff.
So basically, "Are you an insane psychopath that would end an innocent life if you could get away with it?"Yehhhh, no.
Only if he HAS no family. Not saying I would though, but if I did he would have to be someone completely incognito
So why would you want to kill him again...?
Because I can
You can also take a pencil from a classmate and stab both your eyes out with; you don't do things just because you can.
