(I'm halfway through the third season, so try not to get ahead of that.) If you wanted to prove that Korra was indeed a villain herself, then you'd be trying to prove that all hypocrites are villains. In other words, "how can you call this good if bad comes from it?" If hypocrite=villain, then I should agree with you. But everyone is a hypocrite, and you cannot have an antagonist without a protagonist. I say a person is defined by what they stand for, not what they fall for.
I didn’t say she was a villain. I just said her actions caused most of the problems. And that the “villains” were not inherently evil.
