Crazy does not automatically mean illegal. Weird addiction lady eats cat hair. Crazy, yes. Illegal, no.If its not seen as crazy then why is it illegal? Because we as a society have decided that murder is an aborhent act, an act of an unbalanced mind and must be punished in the harshest way possible.
Murder is not normal, and you cant justify it by citing their poor upbringing, or environment.
If a person sees murder as normal, they are crazy. I cite sam as a perfect example.
I'm pretty sure that the gangbangers would not see themselves as having an unbalanced mind. For their environment, they are acting in a perfectly rational, self-protective manner.
