He's a rat. Henry Hill is a rat...Gloryfied by books and movies. Sammy the Bull is a rat, Valachi, Lonardo....all rats. Why would it surprise you that these guys are rats tho?
They have no morals, all they care about is self preservation.

Henry Hill.....do you know the real story? Did you know Paulie was fuckin Karen? Jimmy wanted him dead, and Jimmy was a stone cold killer, and wouldnt hesitate. Is Jimmy Henry's friend? Is Paulie a father figure?

There all scumbags who prey on the weak and eachother. Movies romanticize it. Sure there are some criminals who live by a code of honor, but nowadays that is rare.
