Fishleg said: "to think Hiccup would do something like this even though all his life he have always wanted to kill a dragon to prove himself". That's why in this AU he is a villain, all becuase the pain that he felt in Berk, all because of they
I'm surprised that in hiccup didn't become a villain bc he was mistreated by everyone even if they didn't realize it and stoik his own FATHER mistreating him is really fucked up
