Suicide has never made sense to me.
If one lived in a horrific place where one is subject to torture, I suppose suicide is preferable to suffering. If you're an unhappy rockstar or movie star, it does not make much sense.
I think some suffer depression, whether chemical or spiritual, that just blots out the real world and its grace.
Who was the guy who had the food show, Bourdain or whatever, I read that even on the set he would mutter about how foul and worthless and hateful he seemed to himself.
Tough row to hoe.
