The most pessimistic thing I heard is that if you are the victim of a crime and are forced to defend yourself with deadly force you are in trouble. The criminal would not be in trouble if he lived but you would. What kind of society is it where you have to allow yourself to be robbed or murdered in order to prevent your life from being otherwise destroy. Are you saying that life is that bleak.
If that's your view of the world, you can have it. That kind of a world doesn't seem that it would be worth living in.
