Earlier quoted context omitted.
Suicide is a human right. Interfering with someone's basic right to self-determination is absolutely despicable, no matter how ill the person is.
someone who suffers from suicidal tendencies as a result of mental illness is in no capacity to make these decisions, they're as incapable of making actual decisions as a minor, probably more so and should be institutionalized. The right to self-determination derives from an assumption of someone being in a clear state of mind, that's why we have plenty of conditions under which we withdraw that right.
Anyway, I didn't consent to being born, why shouldn't I be able to choose to stop living?
