I guess I don't know you that well then, because that sounds pretty on-brand to me.

Venat's in a thorny position, because while it's not generally proper to choose suffering for its own sake, especially inflicting that on others, she did so because she already knew the outcome. I'm not really that versed in Nietzsche, but I think the Endwalker time loop is probably the closest a JRPG has ever come to (accurately) depicting the concept of eternal return. It's not really about accepting the idea that things will repeat forever, but accepting that every single event matters in shaping the present, so if things were to repeat, they'd have to play out the same way. Venat simply made the choice to finish the cycle, on behalf of every living and/or dying thing in the universe, including those that had yet to live and/or die, which is really hardcore when you think about it. (Also couldn't resist the Dragon's Dogma quote, sorry.)
