[Star wars] why didn't Vader just kill himself?

After mustafar but before he learns he has a son, he's angry and depressed.  Her fights like a man with a death wish.  Why not just commit suicide?

Anakin/Vader is far to vain to have a deathwish.  Wanting to die implies the problem is either with himself or that he isn't strong enough to bend it to his will.  Vader does not think either thing.  
No, he's plenty angry, but it is everyone else who should die, not himself.  That is the fighting of a man who is angry and thinks himself invulnerable, not the fighting of a man with a deathwish.
