I’m always confused towards Korra fanboys who suggest Aang would have been a terrible past life for her and she would have hated his output to her. Whether you want to take the show’s interpretation as canon or the novel’s interpretation as canon it’s still two of the same where Korra leaned into Aang as the one who helped achieve/found the strength with herself to get her bending and avatar state back. Korra would have absolutely loved for Aang to be by her side in that catalyst event.
