Sora could. In fact, if Chirithy remembers him, Sora is trying to get the gumption up to see if they can't do it again. That's neither here nor there, though.

He does look a bit rebellious at the idea, though. "We can remember that things shouldn't have happened that way, and not do it again. That's what memories are good for." It's the reason why Sora keeps the pain around. It reminds him to be better. Otherwise, he'd be perfectly willing to just toss those memories away and have some fun for once. He needs those memories to be him. These reminders that other people feel pain as much as he does.

He does try to lower his hackles a bit though. Jason's right. Being mad at those gods of his here and now won't accomplish anything except get him mad. (Which is actually an accomplishment in and of itself! It's pretty difficult for Sora to feel anger, even for the sake of others. It's cathartic, a little, being able to be angry for the right reasons.)

"You're worth more than a tool. Way more." Sora shrugs. "If she wanted to do something, she should have just asked you. I bet you'd've figured out what to do right away."
