Thankfully we are ourselves as individuals afforded a freedom that the Ancients themselves were cruelly denied - agency. We're not all obligated to entertain the idea that Venat was the most important and wisest individual ever to exist in the story or pretend that genocide is a sane, rational or justified reaction to Venat's own people not doing exactly what she wanted of them when they were not only in a state of mourning and heartache but also subjected to a 'test' without their knowledge or consent.

Everybody is free to interpret Venat however they so wish. Just as they're free to do the same with the Ancients themselves.
