Dumbledore from the Harry Potter Series
Dumbledore was supposed to be the “best headmaster” of Hogwarts and while we loved him at first, we quickly realized that his character was darker than we initially thought. Firstly, he purposely left Harry with the awful Dursleys. Surely, he could have made better arrangements for “The Boy Who Lived?”
As the movies progressed, it became evident that although he had some wise words, he was only using Harry as a pawn. He also kept important information from Harry like the fact that he would probably have to die in order to destroy Voldemort. Besides, what sane headmaster sends children into the Forbidden Forest?!
