My point is that the difference is what makes the situations incomparable. The generalization to make them comparable is far too extreme. Ultear realized her mistakes after a massive, life-shattering (Deus Ex Mashima) revelation, while Irene... just realized that she had deluded herself into believing that she hated her daughter. That should hardly affect her devotion to Zeref or services under his command, unlike Ultear being robbed of the motivation to achieve her goal.
