Worked almost all of my adult life in mental healthcare.
Seen it all and heard it all. The problem with healthy people who are judging other people who committed suicide, is that they are thinking from a relative healthy mind. I knew people who ended there life and could 100% agree with there decision.

There are people in this world who are suffering every day of there life. Some are depressed, psychotic, are bipolar, ore all three. They were abused as children, neglected, have brain damage you name it. They do things to them self that you can't imagine. I won't go in to details, but believe me it goes further than most people can imagine. Sometimes the voices in there head tell them to do it.

I worked with people with personality disorders (Borderline, narcissists, antisocial personality's and everything in between. I totally agree that these people can damage other people in ways that can't be repaired.
