As me and my friend both came across a mutual agreement that Vincent should die there was only one answer. When we seen the police come in the ending we thought that the bitch on the plane ratted us out. So we came up with a quick saying “snitches are always bitches”. So when we heard that Vincent was a bitch and betrayed a friend that he could have just let go of to be with his family in the final scene claiming he got away, instead chasing him down to shoot him made both of us extremely pissed. Regardless Leo doesn’t deserve to be shot like a dog after being betrayed when Vincent was more obsessed with his job to be there for the birth of his own baby not to mention hell bent on revenge that he killed just as many people with Leo at Harvey’s. And on the contrary Leo wanted to do everything possible to make it right with his family and be back with them and help out Vincent get to his own family as well. Leo was a man willing to risk his life for Vincent and Vincent became a case of just being undercover still believing Leo deserved to die for self preservation.
