And of feelings, Elesse has... rather a lot. Start with the guilt and the shame that her padawan killed herself, and the hurt that Elesse feels because of that. Add more guilt because Elesse contributed to Anakin's problems, by ignoring her, by not making time for her. She was busy, busy running the war. Time that she didn't spend on talking to Anakin was time spent on making sure her troops had a better chance of survival. Add up all their lives on one side, and Anakin's on the other, and then all the Separatist armies that she was fighting and... Where does the scale end up? If she was able to go back and choose again, would she do the same thing? She wouldn't, she thinks. Not at the cost of Anakin's life.
Looking at in from the perspective of the Jedi Code, did Elesse make the right choice? The many lives, the peace the Republic promised. (The looming darkness Anakin hinted at.) Would she be permitted to choose otherwise, if she could go back? Would she even want to. What is one life, against all the galaxy?
It's been a long, long time since Elesse has had to confront this sort of turmoil in her soul. It scares her.
