I don't hold them responsible because they didn't force his hand, he chose to do that, perhaps not as himself because clearly he wasn't himself so I don't blame him either of course, it wasn't his fault that he was that depressed. But if they just made an effort to really hear people, maybe some would feel there's a light at the end of the tunnel. It's the most unpleasant feeling when you're asking for help, but you feel you're being pushed aside, or made out to be a problem, not worth helping etc..
Just thought I'd clarify, as that may have sounded insensitive.
