Both of these things are selfish, by definition, right? Suicide is an act performed by a person to remove them from a world they don't want to be in any longer (self focus). Being upset at a person for doing so is putting your feeling above theirs (self focus). Selfish is inherently a negative word, though. Maybe self focused or self motivated is still accurate and less negative.
