Review Detail of Skull_of_Life in Avatar The Legend of Korra: Ruthless Wind

This is my second review, the first one I deleted because after a while I thought it was hasty. After reading 18 chapters, you can see that the protagonist is pretty bad from a moral point of view, but then again, how bad he is is not clear, and who determines what is bad and what is good? Although I have new questions, I think that you just need to wait, unfortunately, or maybe fortunately, I don't understand what the main character is like in the first 5-10 chapters.
