OK that's your reaction.
But prove to me how killing a person, ending their existence forever is justifiable? You may be "scarred" but there are programs that can help you get over that and you learn to enjoy life again.
Murder should be the only thing punishable by death.
You can get over having your leg chopped off too but would you murder someone who came to chop off your other leg? You're mixing up the external justice process with the self defense process
