No villains or villainous leaders in my books, ever. There's some mythologies, and celestial beings are very prominent. No religions, either. Lots of characters are powerful, often, but not dangerous.
But the big rule, besides no villains, no religion, and so forth, is no character shall ever intentionally harm another character.
Most people don't get how I can write without having evil characters or evil events. There's tension in different ways.
That doesn't mean that the characters don't have dark experiences, but it's all alright in the end, because they choose to have life experiences that are challenging. The game of life, that's what it is.
