If a murderer killed someone I cared about and there was a third party who knew about the intent to murder but did nothing to stop it because he or she wanted me to 'learn to suffer' then I'd quite readily have more contempt for that person than the actual murderer.

Now extend that from murder to the genocide of one's own species...and yeah, Venat's far worse than either Hermes or Meteion as far as I'm concerned.
