So here is the problem, When I made it to level 19 or 20 whatever level it is to get the message of dawnguard Durak one of the dawnguard comes up to me with the quest. I liked his armor and just killed him but as I go to start the dawnguard Everyone their is trying to kill me. I killed most of them except isran and his bald friend with the mage robe. Can i join the vampires by just going tot he castle or I'm i just screwed. I'm playing on the ps3 by the way
