Then there was the time, the callous, crass, stubbornly independent (and occasionally villainous) fighter got killed.
The party had no cleric capable of raising the dead, but they were traveling with one. Problem was, they hated her. She was annoying, petulant, frequently useless (a cardinal sin in the eyes of players!), overly pious, and strictly dogmatic.
And she was, at that time, the only example of a worshiper of her deity that the party had ever come across, so, as far as they knew, that's what the deity was looking for in a worshiper. They also had strong suspicions that the deity, or at least its church, was not as good as it made itself out to be.
Anyway, she cast raise dead on the fighter, but before he could come back, I handed the player a note asking if he [his character, that is] would agree to worship and serve the deity as The One True God. The implication, of course, being that returning to life was contingent upon his answer.
The player was so torn up about this that he actually rolled dice to determine whether or not he would agree to it. In the end, he did, and spent the remainder of his adventuring life as a faithful (in an entirely pragmatic way) and certainly villainous servant of that deity.
