But I dont agree that killing for the sake of killing is natural. It is usually done either protecting ones property, steal others property(including women) or to win dominance and create a new social order.
The modern definition has differed the one thats planted within us since humans walked the earth. People listen and behave according to what the government deems lawful. People have been brainwashed for humdreds and hundreds of years as to how they should act and what others deem as normal behaviour.
Some people - Ted Bundy, David Berkowitz and others - have not only been brave enough to show the real side of human behaviour, but have also shown human instinct as it was always made to be shown.
