I played one character long ago who started off as a pacifistic warrior sage (he honed his martial arts only so that he could disarm and disable unavoidable enemies with the absolute minimum required force), and eventually became a nigh-omniscient psychic and reality warper. He used his powers to bring peace to troubled lands, through a combination of diplomacy, subtle mental manipulation, and providing new inventions to solve old problems.
His first love was accumulating knowledge, and dispensing and applying it to best possible effect (in a utilitarian sense, he didn't care about traditional moral stances). He loathed killing, and disliked unnecessary injury; as he grew more powerful he fought less and less, until eventually he no longer needed to fight at all, and then refused to do so.
As a true god, this fellow's domain would be innovation and peaceful progress. His major act of creation would be a subtle one, instilling all sentient creatures with calm, curiosity, and gentle scepticism. Even the most hot-headed, righteously indignant zealot would have a small, quiet internal voice urging them to reconsider, learn more, and possibly change their mind. Day-to-day godly action would likewise be quiet and un-showy, inspiring new ideas with whispers in dreams, providing solutions to tricky problems in "found" books of uncertain provenance, and that kind of thing. In his ideal vision for the world, nobody harms or destroys anyone else, and people (all thinking creatures, actually) continue to steadily improve themselves, their living conditions, and their environments.
He would consider this mission a sad responsibility. It clearly needs to be taken care of, but it's disheartening that chaos and violence are such prevalent and destructive forces even at and above the level of gods. He could only hope that his influence would help the mortals to grow to such capable and enlightened stature that they no longer need to rely on the gods, nor fear the aliens. He would avoid rhetoric, and try to convince the other new gods to see things his way with reason and diplomacy.

I don't know if any of that will be useful to you, but I hope it is.
