One of my more unpopular opinions is that almost everyone here is that way even if they don't realize it. I don't think you become suicidal without something being wrong internally and/or externally, spoken as someone who has spent most of my life being at least passively suicidal.
(Not necessarily "afraid" of death, but I mean there is a set of circumstances/path of development that at least was possible for them to choose life, and circumstances/development have led them to a place where suicide seems to be the most desirable outcome.)
