I said it weeks ago in some long buried argument in Lore, but I view Venat as an, "Anti-Villain." Much in the same vein as Ozymandias from Watchmen.
The grandest desire to do good, while also validating her own morals and perceived superiority.
I mean, think about it. She lived her life flying in the face of Amaurotine society, to a degree, taking what she thought was good and denying what was bad. She already believed herself above her society.
Her act can be described as cruel, and to quote one of the best lessons ever shown in gaming:
"Cruelty leads to suffering. And when one suffers, it is the way of life to spread suffering. The suffering within builds, until its sound is all one hears. And so when a kindness is offered, it is punished. And a greater darkness is served."
KOTOR2's Beggar Problem
Look at Venat's actions, and then imagine that it wasn't a story where the conclusion of victory was predetermined. Imagine if we'd faced Meteion and lost. What would we think of Venat's actions then?
