God, devil, what's the difference

A common feature of faith is that it tends to be held for keeps; once internalized, leaving it tends to necessitate a 'crisis of faith' or something and long strenuous deprogramming, I mean soul-searching.

It's a bit like something you put on and then can't take off again, isn't it. In this respect, it's like those items in RPG's that become impossible to remove once you've equipped them. They're of course commonly called... cursed items.

Cursed meme, anyone?
