I still dont see it sometimes it seems like he is playing the group into his hand. It seemed like he made it to where Yuna couldn't give up so she could get to Yunalesca so he could get his revenge. He knew that they would need a final aeon and he did nothing to comfort them so if they were chosen they could do it with no regrets. He made it to where they would be outraged so they would fight Yunalesca. To me that's shady.
