The greeks didn’t see it as “wrong” when it came to gods because god were not looked at that way, that doesn’t mean it was socially acceptable in society to be a serial rapist. Gods were not moral beings, they were not looked at as plainly as good or bad or an example of the way their society should live, like say, Jesus of Nazareth. If we’re talking about representing them through a modern lens I don’t think we can gloss over their actions as “it was just spreading some seed”.
There are literal acts of rape depicted in greek stories, we cannot gloss over these things if we’re looking at them through a modern lens. I don’t think it’s interesting to take a literal approach to analogs for greek deities - Zeus is a villain, Aphrodite is a mean girl etc. It’s never interesting or compelling to do “thing good or thing bag” for any character. and while it’s important to be cognizant of original context, use and function of gods to their respective societies, as with any theological or folkloric interpretation, it’s also important to deconstruct and recontextualize for a modern audience. I think Zeus in the part of tyrant king, commiter of incest and rape is fair.
