I was with this movie until.... *spoilers*
He killed the detective...... like come on.... so he had to witness his dad death and killed his brother (in self defense) they were both burdens that was now gone. he had his wife and unborn kid and 5.5 million dollars. the pain of it all wouldve gotten better( i dont think he wouldve ended up like his dad, he was gonna kill his dad for good reason and wasnt gonna kill the brother)
i wouldve kept the money
i wouldve accepted the ending only if after talking his wife on phone he shot himself or died on bench from wounds
