Ahh, classic example of ignorance towards mental illness... I agree, commiting suicide is the easy way out
I've known people who committed suicide, and while yes, sometimes suicide is an impulsive (and perhaps selfish) act, it is often not the case, particularly when the person involved has suffered for a long time with a mental illness (depression, bipolar, schizophrenia). For them it is not the 'easy' way out... but the ONLY way out (from how they see it). Mental illness distorts how people view the world... they don't see it like you or I would, and they often cannot see any other way to end the pain.
Furthermore, people often assume it's selfish, but actually it may be quite the opposite. One person who I know who killed herself had said on many occassions that her family would be better off without her, without the burden of caring for her and watching her suffer from her disease. I really believe that when she killed herself she thought she was doing it to help her family, as well as end her own suffering.
