I look at suicide as a fear of death, as ironic as that sounds. To me, suicidal people feel as though they have a loss of control, such a loss to the extent that they feel without that control life isn't worth living. Therefore they decide to kill themselves as an act of final and outstanding control. It's more or less the ultimate act of stubborness, there's no debating death, and when it's self inflicted than it's seems a good way to go out because it's by your terms.
