>Amon
- Wants to take away peoples bending and create an equal society
- Nonbenders can still have bender children, so his plan is doomed to fail OR he has to pass down his bloodbending techniques which is the entire reason he hates bending
>Unalaq
- Wants to become the DARK Avatar and free Vaatu by getting Korra to open both spirit portals
- Gets her eating out of the palm of his hand, then betrays and directly antagonizes her before she opens the second portal
>Zaheer
- Wants to remove all authority so people can be free
- Creates a power vacuum for a tyrant to step in, also even if he did succeed he falls for the Amon trap where he has to keep on continuously killing new leaders challenging his reign of terror, essentially becoming what he hates
>Kuvira
- Wants to unite the Earth Kingdom
- Does a bunch of retarded shit and starts pogroms against Earth Kingdom citizens, dividing it further and sabotaging her own military efforts (which is again sabotaged by her decision to create a stupid mech)
Is there a single villain in Korra whose plans don't defeat themselves (except Lin Beifong)?
