Suicide when done for notoriety or self-righteous fundamentalism can be very selfish. He traumatized those who witnessed and cleaned up after him, put his pain on those who now grieve him, and stochastically inspired other mentally vulnerable individuals to act out. All because he had an unshakeable belief in his pessimistic worst-case-scenario viewpoint being the absolute truth of how the world is and will be. Is that not irresponsibly self-centered?
