When we criticize the suicidal for being selfish, we are actually criticizing them for not enduring their pain with grace and good manners. These are nice qualities; we may be correct to reproach average citizens for not having them. But to expect everyone in pain to have them is unrealistic. Bearing pain quietly is what moralists call a supererogatory act--an act that is above the call of duty. Expecting everyone to who is suicidal to behave in a way that is morally above average is simply abusive.
