It all about self esteem:

People do things for many reasons but most of the time when you dig deep into their lives you find out that they have self esteem issues. I know that when people don't value themselves they do more to harm themselves. But most of these people do not believe they have low self esteem. If there was a magic potion that would help people love themselves and to stop drugging, gang-banging, killing, raping, lying and just plain harming themselves, I would be the first in line to buy it for the anybody who needed to find love in themselves.

Wouldn't it be a better world.......?
