I think everyone has thought of it at one point in time in their life, or at least thought about the idea of it. Also, there are some people that are born mentally troubled, who are destined for suicide. I recently caught a HBO documentary about a kid born depressed, and was thinking of Suicide at around the age of 5 or 6. Inevitably, he did kill himself at 15. A very eye opening documentary to say the least. People shouldn't judge others about why they committed the act, or say they are weak, selfish, etc. You aren't them. You have no right to assess their life or mindset. In the end though, it's not natural to kill yourself. It's not in our genetics or normal mindset.
