The 79-year-old actor, whose career was beset by HIV rumours in the 80s, said Charlie is getting what he "deserves" because he misbehaved in the past, reported Female First.
"For Charlie, no, he deserves it. He misbehaved badly. Very badly. But you know when you're that age, it's tough. All those things are coming at you and it's difficult."
Burt said he is a close friend of Charlie's father, American actor Martin Sheen, and he is sympathetic towards his situation.
