[He is indeed - the entire reason they're here is for a granted wish, isn't it? Katsuki spoke his desires and he feels guilty for it, the desperation of the moment and the want to live long enough to reach his intended goal, to achieve his dream.

It's never been what he's wanted. It's never been the sort of person he is, despite how talented he is. All of what Katsuki's done for himself...he's done for himself.
