me: you should kill them, if you don't they will either escape or a corrupt lord will pardon them
MC: nah i'll take them alive because i'm such a good guy
*criminals escape*
MC: *surprised Pikachu face*
seriously though why are all isekai MC's such retards? JUST KILL YOUR ENEMIES AND BE DONE WITH IT, all you do by taking them alive is opening up further trouble for yourself and others.
