“Power attracts pathological personalities. It is not that power corrupts but that it is magnetic to the corruptible. Such people have a tendency to become drunk on violence, a condition to which they are quickly addicted.” ~ Frank Herbert, Chapterhouse: Dune
It takes the will of a saint to be incorruptible — to not become addicted to the exercise of power. Those who do not desire power, like saints, may have it thrust upon them.
Even when left to own devices, a person can only exercise power within a society that has desires, wants, and fears. The whole society would need to be incorruptible. This is improbable. In the unlikely case of such a pure society, it would also need to be incorruptible when in contact with “the other” — peoples, species, events, and ideas. This is exceedingly improbable. So, the whole of existence would need to be incorruptible.
There are a lot of godlike beings who would be objectively the best choice.
Lucy (2018) - some mild insanity, remorselessness
Genie from Aladdin (1992) ‐ everything is a joke
Bruce Almighty (2003) - can’t actually control himself
I’m going to go off on a comic-book tangent here:
Wielder of Infinity Gauntlet (1991, 2018) - potential insanity, later radiation scarring
Phoenix Force (1976) ‐ heavy insanity, desire to consume planets (see: Dark Phoenix Saga (1980), (X-Men '92, S03E11), Avengers vs. X-men (2012))
Omega-Level mutants - tendency toward megalomania (see: Jean Grey, Magneto, Kid Omega, 4 horsemen of Apocalypse… even Ororo Munroe (goddess), though Iceman seems well-adjusted)
Beyond - remorselessness, destruction of universes (see: Secret Wars (1984), Time Runs Out Event (2014))
You’re getting their powers, not their personality. Of course, the old “absolute power corrupts absolutely” chestnut applies.
My preferred quote on this line:
It takes the will of a saint to be incorruptible — to not become addicted to the exercise of power. Those who do not desire power, like saints, may have it thrust upon them.

Power corrupts.
