I can't judge either of them. I can't say it's not someone's option. To them, it definitely is. To me, I would be afraid of what may happen if there is an afterlife. I may have to come back and do this all over again. (No way would I want to!)
A friend of mine recently told me she was planning suicide. I told her I wouldn't judge her, I hoped she'd reconsider, and I thought God would forgive her. I prayed for her to reconsider and that she'd get at least some sign of hope. She hasn't done it, thankfully.
It's not that you want to hurt anyone else. You just want the pain, the whatever, to just STOP. As someone who typically blames myself for EVERYTHING, I can understand how it feels like there's no way to stop the pain. And maybe there isn't. But, I guess learning to cope with it differently, in an ultimately much less harmful way, is the better option, not the ultimate one.
When I hear about these sorts of things, I just pray they're not feeling pain anymore and that their families are OK.
