He doesn't know how to love. I have no doubt. Because no one gave him true love, maybe some people in the orphanage began to make friends with him, but when he showed his talent for magic, they were afraid of it all and alienated and ostracized him. He might have really done something wrong, but the little wizard can't control his magic very well, so this might just be an accident. Harry Potter, didn't he also put Dudley in a snake cage?
Gradually they left him. Gaining and then losing is far more painful than never gaining.
His childhood was shrouded in shadow, devoid of love and hope.
When he was a student, he experienced the darkness of human nature from the very beginning.
If you don't have a noble status or outstanding talents, then you are just an ant at the bottom, still being manipulated by others.
He studied hard, he changed, he pretended, he learned to pretend...
He has been living in the shadows, filled with apathy.
When he gained strength, when they all came to curry favor with him. Who is sincere? Everyone just valued his value and wanted to make profits. His handsome appearance only attracted a group of superficial and self-proclaimed girls.
When he finally caught the clues about his family, the truth bit him hard.
The decline of the mother's family and the ignorance of the father's family. He killed his father, his uncle, and the family worker, and the tragedy unfolded...
Concept: One tragedy arises from countless tragedies. As villains, are they destined to be wiped out? Or are they really the villains? How did they become who they are? No one cares, this is justice, so-called justice.
