As for those bringing in "you're ruining God's plans" into the mix: God, if you believe he exists, is . He planned for suicide. If he didn't, he's not omniscient, or omnipotent.

First of all, free will. It can't be removed. It can be dampened, a lot, but not removed. Second of all, in a universe of chaos and free will, a plan can fail, and omnipotence is something we assume has the same meaning as god-like, even if, well, it isn't true.
Sorry, sorry, cool like fonz, cool like fonz.
On topic, it is not selfish to commit suicide, but it is infuriating. It also evokes those weird emotions that regular feeling humans have.
