I'm guessing they weren't quite in despair, they figured God isn't watching anymore so to hell with it. Just do whatever immoral thing they can get away with. Even Chippy and the Indian. I figured their current lives were pointless and they figured offing themselves without God watching and judging, gives them a free pass to heaven.
Then again, they probably saw how shoddily heaven was being run (with that crappy imposter and no HD - that video of 'God' was pretty Low Def) and figured to hell with it. Pun intended.
