I say we outlaw bloodbending. Not only is it highly frowned upon by basically everyone in society, it's an immensely powerful, master-level technique that can only be performed by the most elite water benders under a full moon. In order to be performed in the day without the full moon, it requires one to be from a very specific bloodline (Yakone's bloodline), which (spoiler alert) completely died out with the death of Tarrlok and Noatak (assuming Yakone never had any other kids before he perished in the southern tundra).

Do we want to have the antagonist to be someone Rosai knows? At the risk of spoiling season 3 of Korra (skip this paragraph if you don't want spoilers), we even have the option of the antagonist being a spirit instead of a regular bender, due to the portals at the North and South poles now being open. Perhaps a vengeful spirit seeking to close the portals?

Additionally, if you need someone to play the antagonist, I'd love to portray them.
