Did Zodiark ever do anything wrong?

doing whatever the 'will of the star' actually means

I assume this is stuff like sealing Ultima, the High Seraph originally before Ajora released her, since that's attributed to Hydaelyn herself. Truly, if we're making stuff up that isn't in the text at all, Hydaelyn has been staving off interdimensional incursions from other beings like the High Seraph all this time.

This gets to something that's largely a different thread discussion, but I think what it comes down to is that Venat's ONLY option was "preserve the world until This Particular WoL shows up and has a meaningful chance of succeeding against Meteion." Which meant that EVERYTHING throughout the history of Hydaelyn that threatened the stability of the star was up to Venat to manage.

Remember that part in the Praetorium where Hydaelyn soaks two casts of Ultima to keep WoL from dying and says she can't soak a third? Now imagine how much power she had to dump into subduing the High Seraph and then sealing her away. It's a ton of things JUST LIKE THAT, that the WoL couldn't have possibly told her about because the WoL's knowledge of the star's history is going to be incomplete, and Venat had to be ready for ALL OF IT.

Venat's only option was "SURVIVE."

And overall, that's because the game couldn't paradox itself out of existence. The game HAD to do the time loop and force Venat into that situation because the implications of them just being able FIX ALL TIME would deflate the stakes completely.
