Complete Monster: Johnny Wong tops John Woo's other villains in terms of sheer nastiness. He has absolutely no qualms in blowing away innocent bystanders who are unfortunate enough to get in his way, as shown during the very first shootout of the movie. He only gets worse from there, culminating in the hospital sequence where he kills patients for trying to escape the hospital, takes a room hostage, and fires on the SWAT team even as they try to evacuate the babies of the hospital's maternity ward. Johnny's most despicable act is firing his Uzi into a crowd of patients standing between him and Alan, and then killing his Dragon Mad Dog when he blasts the gun out of his hands. The following quote by Johnny during the hospital sequence says it all.
Johnny Wong: There is no room for failure now. The innocent must die!
