When the finale ended, I have tried figure out Amon's true purposes.
Did his father's curse get to him and that's why he's trying to take Republic City and avenge Yakone.
Or does he truely think bending is evil and he covers his identity in order to "take" bending away with bloodbending.
Or is it a mixture of both. Or something more elaborate.
Please give me feedback of your ideas and solutions.
