I did that wrong. I meant people who do commit murder. And I mean without mental illness by sane, I guess. It really doesn't have a definition.
so basically something something stuff and other things
I think so. If a dude killed a guy's wife and kids, and the husband finds the murderer and kills him, does that make the husband insane?
Depends on too many things for us to talk about. I don't know much about what happens to a person in situations like that anyway.
What I can say is that one probably doesn't act very sane if they just saw their family get murdered.
