My brother is 14 and has told us he keeps having bad thoughts that won't go away.?

I mean like thoughts he wants to break his glasses and then what does he do he broke them! He said he don't know why he does not want these thoughts. He is a good boy we don't know what is happening we think he might have ocd, but can you have ocd and it's only compulsive thoughts? That what he has just thoughts that won't just go away. He does not wash his hands a million times or anything else just his mind he said makes his keep thinking about bad stuff over and over. My mom got him appointment for counselor. Will they be able to help him. I feel so bad for him. This is not his fault how did this happen? Does anyone know anyone with this problem?
