I guess because all his actions were kinda justified and fit his persona. I mean, he let her go with good intentions, and he didn't love her. It takes a bit more for people to love, and he is one of those people, and the way he was in the jungle, it was because he was mad at the situation which he couldn't express so he was aloof with Nakku. Yet in the end, he came around.
I didn't loose my temper when he didn't go get Nakku after Kala said all that, but thats because he was hurt. It hurts to be reminded about something like that, and then, I am sure, even without the video, he had made up his mind to go get Nakku, but the video fueled his fire.
Now, how he acts after the reveal might make or break what I think of him. Lets see how he handles that, and how us girls take it. LoL.
