The Satan's Choice MC hitman Cecil Kirby who worked for Cosimo Commisso in Canada from 1976–81 wrote in his 1986 autobiography Mafia Enforcer: "Cosimo wasn't tough-he was homicidal. He'd kill you as soon as you were looking at him if he thought you were crossing him, if he thought it was good for business, or if he thought you insulted him or his family. The lives of other people meant nothing to him".
