I want to kill myself?

I would call your mentality as "Wise". The person who realizes all the bad things like you mentioned, all this hate and crime, is smarter than 90% of the world. Now, instead of trying to find more knowledge, your job is simply to live with what you know, and try your best to stop the hate. Knowledge brings power, but pain. I feel sorry for, but at the same time glad that you have evolved mentally to a stage where you understand why people like you and me try to change things, and constantly battle against not only the world, but the despair that lies in our own hearts. I hope you make it, but if you don't, I know I won't think any less of you. The only reason I'm still here is because my old revolver jammed when I pulled the trigger.
