That's actually a great idea, because I think suicide has a "good of the collective" component to it. If you get rejected by your peers too much, ostracized and made to feel like a burden, your mind comes to the counter intuitive conclusion that the best way to ensure survival of your tribe is to die. Transplanting to an environment where your knowledge, ability and assets make you the most valuable and looked-up to person in the community might reverse feelings of rejection, ostracism and burden. This guy sounds like he has been rejected and ostracized for everything he did.
"Most valuable person in a community"? Xenophobia is pretty strong, especially in places with few resources or under oppression. Not many such places would welcome a meddling know-it-all outsider.
That's interesting. One of my friends has a theory of a "social discard program" that she's been blogging a lot about recently. It's basically just noodling along the same lines:

Ostracism (parents, girlfriend, job) causes depression, advanced depression causes suicide.
