I don't think he's hypocritical. His feelings changed. He's never been a vengeful person. When he first woke up after being left for dead, he was hurting and angry. He wanted them to pay, to suffer. When Athena's death just made him feel worse, it put things in perspective. I think he lost his taste for vengeance because he finally allowed himself to process his feelings and reconsider what would actually make him feel better.
Of course hes mad because he's hurt, but didn't you read it a while ago, why he had a change of heart? Especially when Athena died, although he did not cause her death entirely, he still blamed himself someone innocent died because of his revenge..
That's also what Rosamel asked him- why care for a little collateral damage? then Vidura explained his back story ..

Am I the only one who kind of feels like Vidura is kind of a hypocrite? In the beginning he was all like "I'll make them pay, I'll get my revenge!!!" But now he's all sympathetic and ready to let them go???????
