> Nobody is directly responsible for Swartz's suicide but Swartz.
Numerous courts around the world have put responsibility on third parties pressuring victims into suicide. Cult gurus pressuring people into (possibly mass) suicides, companies and managers for their employees suicides, and individuals pushing their own parents to commit suicide for will benefits.
Responsibility is a nebulous concept. The extent to which a clinically depressed person (if indeed he was) can be said to "be responsible" for their own suicide is pretty debatable.
Supporting your (hypothetical reasoning, yes), I'd rather say that it is in most cases inexistent (at least from a relevance point of view): the urge can be so overpowering that 'responsibility' becomes almost meaningless.
That is why support is so so so so so so so important.
Actually, I think it's reasonable to say that if someone is so depressed, their responsible diminishes as the pain deepens. It's a terrible thing and if he was unwell he can't really be classed as responsible surely?
There have been a few people in my life who have committed suicide. Knowing what they went through, feeling it a lot myself, it often feels like the only way out, the only way it will bring an end to your pain. It's not true but it feels totally like that, like you have absolutely no option.
