I Hate My Brother Sometimes

He made a horrible remark today about how he beat up a disabled person for fun. I was shocked to hear this as I am disabled myself and never thought he could do something like that. I digged in a little deeper about it and it seems last night he was making fun of this person with one arm. Trying to provoke him in the pub or get a raise out of him. He poured lager over his head and it caused him to swing at him. He took this as opportunity to beat him up in 'self defense' I felt sick to the stomach.
