Moash always chose the immediately gratifying choice: Destination before Journey. He chose killing the ones he felt had betrayed him, instead of protecting the ones he hated: Death before life. He chose resentment and bitterness instead of strength and honor. He ‘gave up’ his humanity. Weakness before Strength. It’s been Moash all along. As long as he blames everyone else for all his misery, he is an easy prey for Odium.
