What would you do if your girlfriend was raped by a gang of ruthless bastard? If the tortured her? And ended up killing her?
Would you see the kitchen knife in the knife block, pull it up and run your finger along the blade while you fantasize about cutting it in the belly of the rapists as just punishment? Would you do it if you got the chance?
Does it make any difference if we turn gender roles, and you are a woman who sees your husband being mistreated and killed? Or your child?
