The saddest part about this whole story is the MC despises killing and violence. He is turning into his father by force just like his dad wants. He is slowly trying to break down his mind & spirit till eventually he won't feel anything anymore once he take a life. He will no longer try to find ways on how to go by winning with the least damage possible because he's father is constantly pushing him to either be killed or kill. His father faith in him is super strong he knows can't no one beat his son. This is just target practice he is sending to his son. Even if he kills every gang member there in the end his father would've still accomplished his goal which is turning his son into a killing machine. He still would constantly have a target on him for life & probably resulting in him having to take over the family business eventually because he isn't going to be able to constantly protect everyone by himself.
