Anderson kind of understood he couldn't kill Alucard from previous fights. He had to have a plan to kill Alucard, which was one of the Nails that held Jesus against the cross. They were rivals who became friends. This is from how they both yearned for death, not being human anymore, in which, they were less than humans. He wouldn't attempt to kill Alucard during the flashbacks, from him wanting to have a fair fight among monsters.
