I don't believe in Revan being THAT popular. It's not profitable for the Mafia to kill him because his behavior attracts suspicion to himself, which the previous game clearly demonstrated. But a maniac might kill him to avoid future problems, or the Mafia might kill him. After all, it's very important for the Mafia to know who they are killing in order to maintain the balance of power.
