I'm pretty sure people have thought of this before, but I haven't seen any posts or threads on this idea. People are going on how naruto has to get something to defend against amaterasu, and a bunch of other stuff. But here is my idea.
When sasuke used amaterasu he was under A LOT of stress, and that triggered his emotions, and those emotions remembered his former team and how he wasn't alone. That was sasuke's "emotional" amaterasu, which is dependent on those emotions, then the ability put out amaterasu was based on his emotions which wanted to save someone(same with amaterasu sort of), this suggests that it REQUIRES those emotions.
I think that Sasuke will come to konoha and try to destroy it via amaterasu, but he won't have the emotions which triggered the original "emotional" amaterasu, and he will **** up and not be able to do anything, because he isn't trying to save anyone, and the remembering that he wasn't alone wouldn't count because he would be killing
