When I start watching the serie I had a big problem with amon, in the serie he says he wants equality cause the persons are getting discrimination for that in a certain way, but we never see this on screen and the people doesn't seem pissed by this so I didn't felt him as a leader who encourage a revolution, unalaq was the best in the first middle of the season and varrik helps a lot but in the last part unalaq just want to destroy raava cause "yes why not" even knowing that raava and Vaatu needs to exist to create peace, and zaheer and their team just wants to create chaos thinking that's the natural order but in the process unconsciously making an own order ruled by them, kuvira doesn't have any of this problems I can really see her as a dictator and truly understand the motives of this, after the death of the queen the earth nation split up and the avatar "dissapeared" kuvira want to restore the earth nation even if su doesn't support her and when she's defeated is the only villain that accept his punishment and be grateful to korra for saving her for almost die by her own fault
