In a tribal society, the chances of them being fine would be greater than in the classic nuclear family. So it depends on a lot of other factors. I'm not 100% sure how to interpret evolutionary minutiae in human society past the basic agrarian level. Factor isolation becomes quite difficult. E.O. Wilson effects come into play. If I may, the Stoics thought suicide a perfectly acceptable reaction to being "checkmated" in life - if there was a significantly unresolvable ethical dilemma, fall on your sword. The Stoics were the principal competitors to the Church early on, which led to proscriptions against suicide ( some say ).
