Tom Hagen vs. Carlo Rizzi

Like many small time petty crooks, Carlo didn’t like to work and wasn’t good at holding a job. Not only was he lazy, he wasn’t smart. He made mistakes as a bookie and his co-workers had to keep an eye on him.

He was the guy who married Connie Corleone and abused her, using one episode of abuse to lure Sonny into the trap where he died.
