as for the villians, i kinda prefer my villians to be old skool evil. unapologetically cheesy ass evil. without being stupid evil as in totally chaotic evil. but that's just me.
now if you look at the plot in different way , you can say the main villians in all 4 season of LoK found redemption. meaning the main villian in S1 is not the racist but his brother, and S2's villian is varick and not the darklord-wannabe.
varick always half-redeemed himself for his selfish actions by helping team korra here and there, but things never would have screwed up as much without his behind-the-scenes manipulations, so he is in a way a bigger villian than the darklord. some might say he's more "evil" just because he did it for FUN 'N' PROFIT!
as for amon's bro, he wasn't as honest and straightforward as amon. making him a more ignoble prick. in addition, he was in a position to create a relatively "equal" society in the city, but all he wanted was more political capital. but yeah, he redeemed himself by regretting his actions and offing himself along with the racist.
