I don't think you can really draw a line between "acceptable" and "unacceptable" just like that. With law, you have things like diminished responsibility or self defence - it isn't excusing the crime, it's just showing that it wasn't cold blooded murder.

Question evasion aside, I think just the obvious stuff; if everyone's obviously going to be a lot better off with someone dead, then I suppose it's "acceptable" to kill them/for them to commit suicide.
