A little back story here. When my main character was twelve, his parents were killed by monsters. A monster hunter who has been tracking them finds the main character (spared due to his age) and gives him a choice, he can either stay there and wait for police or he can come and get revenge. For my purposes, he chooses revenge. Pick up where the actual story starts. My main character is now nineteen and an accomplished hunter. But he gets cocky and is infected with the disease that will make him into one of the monsters. Now, after spending seven years fighting them, would it be even remotely possible for him to really become a part of a monster family? Or is it unbelievable?
