""And it's also a lot about how he handles tough situations, for example, when Korra loses her memory""
Yes. And in those next 2 seasons, he has grown to be a better person. Just like Zuko. Sokka started out as a sexist and I didn't like how he handled the situation about the Kyoshi warriors in the 4th episode. However, he grew. Just like how Aang acted childish when Sokka and Katara met Bato. He grew. I don't understand how you dislike Mako when other characters are in the exact same predicament but you refuse to dislike them.
