Amon was a perfect example of the character-creating logic, "you only need a reason, not a good one." He was a highly internalized character. I feel that the themes of abuse, mental warping, diluted personal perspective and misplaced ventilation of rage for his motivation are all over-looked. I've had this same discussion with quite a few fans. What were you expecting from Amon? What did you expect his huge reveal to be? He didn't have megalomaniac plans to take over the world or destroy it, nor merge it with the Spirit World. He just wanted to rid it of bending, granted that's on the opposite end of the spectrum, but it was fueled via political and internal strife made by a society where some are gifted abilities. It's a natural oligarchy of sorts.
I still feel like the Red Lotus was more of a tool than anything, which made it hard to... respect. You literally see one character follow through with its morals and have any form of character development while you see Amon shape Korra as we know it is now. I also feel like saying Unalaq had a one-track mind isn't lending enough credit to his ingenuity with manipulation, geo-political analysis and manipulation and overall skill. Unlike every OTHER villain, his key ability was to soothe/control spirits using Waterbending techniques essentially anyone can learn. Two airbenders have flown. Only a handful of waterbenders can bloodbend. In all reality, he's probably the most 'realistic' villain in terms of what he does and how he does it.
