And on the relationship the cleric and deity have. If, for example, this cleric has been routinely very good at carrying out this deity's described doctrine, and doing so with subtlety and wisdom rather than as a blunt object, why would that lead to such horrible wrathful deific behavior?
The only reason I can see is "GM wants to punish the player, exploiting a convenient excuse which allows them to do whatever they want scot-free".
Which I was--
extremely recently--told
by this very poster, Maxperson, is apparently not a thing.
So,
@Maxperson, which is it? Are deities (and patrons etc.) used as cudgels to control player behavior? Or are they included genuinely for flavorful, story-promoting reasons, and negative consequences
only arise because of genuinely warranted circumstances?
Because it would, 100%, look like a punitive GM vindictively punishing a player for a behavior the GM simply finds distasteful, but not in any way actually
wrong or
bad, to bring down divine wrath for such a petty reason.
Especially if the possibility that this kind of thing could occur were not explicitly spelled out, right out the gate, before character creation is finished.
