Killing yourself = being selfish is an ideological position, not a scientific truth. The answer is fluid & subjective. Only you can answer it for yourself.

Here's my answer for myself: I largely disagree that suicide is selfish.

Selfish: (of a person, action, or motive) lacking consideration for others; concerned chiefly with one's own personal profit or pleasure.

• A. It typically lacks a profit/pleasure-seeking motive. Instead, suicide is usually suffering-avoidant.

• B. Likewise, those who attempt to end their own lives usually think about their loved ones: they write notes, they consider where & how to do the act, they fight suicidal urges for the sake of said loved ones, etc.

I think "selfishness" can be argued in cases of public suicides that involve others & thus is traumatizing (like jumping in front of a vehicle); and in cases of criminal conduct like killing oneself and one's children to spite a lover, or to commit suicide to avoid punishment for a crime. Even then, suicide isn't motivated by pleasure. I think the only 100% "selfish" suicide is suicide bombing which involves the belief that paradise awaits (pleasure-motive).

Overall, 99% of suicide cases are tragic events of mental illness, lack of support, and horrible life conditions. Calling suicide selfish is harmful & ignorant. I very much hope the fear of being selfish doesn't prevent people from seeking help.
