Troubled Souls (Pete Wentz Vampire Au)

Every city has dangerous things going on during the cover of night, some worse then others. Everyone blocks it out if possible. For the ones who got to see what lurked within the night and survived, it opened a whole new world. Ether they locked themselves up and went through a life of fear or they stepped up and tried to do something about it. Pete just happened to see the horrifying side of the night as a teenager and vowed to try and protect the innocent. What would he do if he ended up the same thing he vowed to kill. Would he end it for himself before he became a monster or would he use it to his advantage?
