Responding to TauPhi , in relation to gods' moral/ethical incorruptibility, I'd say it describes their ability to never make any choice that dilutes or decreases their pleasure. They don't have "temptations" for lack of a better word like us mortals.
But I'll lay my cards on the table:
I don't believe in any gods.
Whether Epicurus taught there were physical gods or he thought of them as metaphors is secondary, to me. The most important aspect of Epicurus' teaching on the gods is that even if there were gods, they have no impact on the blessings or misfortunes that befall me in my life. Any thoughts I have about the gods of a one-way interaction.
If I want to imagine a perfect state, I can do that. If I want to call that perfect state "godlike", fine. But that *is* metaphorical.
Putting ourselves in Epicurus' headspace and social context in this topic is nigh impossible given our current understanding of the universe. Those tenets of "1. gods don't bestow blessings or curses. 2. There's no evidence the universe is created or sustained or administered by gods" are enough for me.
