But according to DnD he is labeled as good. The real problem here is alignment getting in the way.
whoops, my bad. In 5e Zeus is Neutral, in 3e he was CG, in 1e he was CG.
Funnily enough, he's never evil. My point still remains. The problem here is that people are insisting that as soon as you slap a Good alignment on something, it cannot ever do anything evil. Even failing to stop something evil, or, not doing anything to stop evil, makes you evil.
It does go a long way to explaining why these conversations go around in a lot of circles.
