Are you familiar with the story of Jekyll and Hyde? It's about a this good man had a monster lurking inside him and comes out from time to time, wreaking havoc. The control of that monstrous being inside of him was impossible.
Bruhom had always been a good man. He'd only harmed those who tried to harm him or others. He didn't go looking for a fight. He wasn't an aggressive person. He'd watched me grow up and often was like an uncle who wasn't related to me.
He only broke things if it was by accident or if it was necessary. He never seemed to get angry unless it was time to get angry. He could never have been described as a beast.
