A lot of people that feel strongly about suicide have had the idea from a young age. Not that some people can't develope it later due to miserable circumstances. But I know the Winko type and some brains just aren't wired right to feel joy. He likely felt that way since he was a child and probably would have felt it till old age.
Yes there were things that could have been done or tried to make it less likely but who are we to know what he actually did or didn't try. Chronic clinical depression is fucked up...a continous cloud of misery 24/7 and inability to be happy. Energy always low, unable to be motivated to live and to even wake up. The nothingness of sleep being the only temporary relief. The feelings of loneliness being as miserable as trying to not be lonely, causing further isolation. A majority never do find relief.
