I’m not a fan of his either but suicide is a terrible tragedy(and a selfish very hurtful thing to do).
Terrible tragedy, yes.
As far as selfish goes, most of what people do is selfish in one way or another.
If you got married, had kids, contributed to a political candidate, go to church every Sunday, give to the poor... if you look deep enough, there's a selfish reason of one kind or another.
A healthy life, in fact, is built on a healthy degree of "selfishness."
Suicide is an effort to escape pain. People who are suicidal just want their pain to stop. They have decided that there's no pain killer on earth that will stop the pain, and the only recourse for stopping the pain is death.
So yes, they're probably thinking about themselves and not so much about other people. But it's hard to think about other people's feelings and needs when your hand is on a red-hot burner.
The person that commits suicide never says it's a selfish thing to do, at least none that I know about.
The U.S. government/taxes, the medical establishment, and the family that has to pay the funeral bills etc. might say it's a selfish act under their breath. Other then that I don't see it as a selfish act, I think that is something our medical establishment has come up with so they can keep seeing you and selling you the happy pills.
