The true holy war isn't religion, or even Good vs Evil. It's wisdom vs stupid.
If you think about it, there's absolutely no reason to classify anything any eternal being does as good or evil, that's just a human interpretation. So framing it as a battle between good and evil essentially implies that infinite beings would battle for human perception, not anything in reality.
So battle of good and evil would purely be for human perception, and maybe that's always why the stories we like are good and evil, and anything in reality is way more complicated right now.
Since most interpretations of an infinite being or an infinite existence usually describe it as an order of some regard, even if its indescribable. So the true enemy of that could only be the genuinely nonsensical. An action without purpose in a world where every action has an equal and opposite reaction.
And as more and more people feel like we live in the end times, we can all look around and see that this is REALLY stupid most of all. Maybe the true test is if we can put our differences aside and take out the stupid first, and then chat about the good things like the true good old days.
Remember when Jews, Muslims, and Christians were like best bros in the science fields?
CAN WE ALL AGREE THAT WAS AWESOME AND FIGURE OUT HOW TO GET BACK TO THAT?
