Omnipotence still have its limitations. For example, can a god create an immovable object? Which doesn’t make sense because the question itself is contradictory. So that begs the question, is it even possible to be entirely good while still being totally authoritarian and eugenics?

I think you are getting the wrong result out of that argument here. Because if omnipotence can’t exist, and any limitations would mean that it can’t, then the Christian (or any monotheist) god can’t exist, and that effectively ends any reason for further discussion on that particular subject because the foundation of that religion has been removed.

Anything else would merely be thought games on fictional premises.
