Chris Brown thinks it's unfair that Jay Z got ''a pass'' for selling drugs and stabbing somebody.

The 'Fine China' singer, 24, who has had several brushes with the law since he assaulted his ex-girlfriend, Rihanna, in 2009, doesn't know why some celebrities are able to move on from their bad reputations and wishes people would be more forgiving of his own mistakes.

The R&B star told the October issue of Jet magazine: ''No disrespect, because I'm a fan, but nobody brings up the fact that he (Jay Z) stabbed somebody and sold drugs. He gets a pass.''

The 'Magna Carta' hitmaker, who previously admitted he became a crack cocaine dealer in Brooklyn, New York, when he was 13, pled guilty to stabbing record executive Lance 'Un' Rivera outside a nightclub in New York City in December 1999, and he also shot his brother, who was a drug addict, when he was just 12.

But Chris claims he is working hard to deal with his own issues, including seeking help for anger management.

He said: ''You have to go through the struggle before you can get to the good part. I don't try to lash out at people, or be as mad or impulsive as I used to be. I got to the point where it's only so much you can take from the master, you feel me? I've taken my fair share of lashings.''
