He's working very hard and very successfully to build an ever bigger and stinkier cesspool to wallow in. He's getting a perverse pleasure out of all this, so there's no way he's going to change his behavior.

Every statement he makes and every action he takes is carefully crafted to make things worse, because that's what he enjoys. When reality doesn't suffice, he invents enemies out of whatever scraps he can find - the more enemies the better - real enemies (in short supply), fabricated enemies or imaginary enemies are all good so long as he can whine about them.

Threats of suicide are just a cheap trick to get attention, as is suicide itself. Preferably you survive (lots of attention), but if you don't, you go out enjoying the remourse you imagine the world will have for not having treated you better.

The cure for suicide is the realization the world isn't going to have one molecule of remorse - it's just going to be slightly annoyed that you left it with the bother of disposing of the remains of a moron who wallowed in his own stink.
