is it right or wrong? that is a tricky question because there is no ultimate right or wrong. I guess you are asking me my personal opinion, rather than for an objective fact.
I think that suicide is ok, as it is the person's choice.
while, as I study psychology, it is my responsibility to do whatever I can to stop it including informing the authorities.
that is the short answer.
long answer is it truly varies from case to case.
If a person was the last human alive on earth, I think suicide would be justified.
however, if a person just broke up with their boyfriend and is threatening suicide for attention, it is obviously wrong.
also, we do have a responsibility to help those who cannot be cured live as comfortable a life as possible.
ex. we give people with schizophrenia anti psychotic meds.
we give people on their death beds morphine.
