Anyway - I found this.
It’s not the most robust or “killing” literature, considering that it’s taken from a law and philosophy journal, but it certainly helps frame a convincing argument that no reasonable person would disagree with.
In this chapter, we ask three questions about pedophilia: (1) Is it immoral to be a pedophile? (2) Is it immoral for pedophiles to seek out sexual contact with children? (3) Is it immoral for pedophiles to satisfy their sexual preferences by using computer-generated graphics, sex dolls, and/or sex robots that mimic children? We argue that (1) it is not immoral to be a pedophile, (2) it is immoral for pedophiles to seek out sexual contact with children because of (and only because of) the expected harm to children, and (3) it is morally permissible for pedophiles to satisfy their sexual preferences in ways that do not involve any real children.
