Chronic sexual predators [to Vachss, pedophiles] have crossed an osmotic membrane. They can’t step back to the other side - our side. And they don't want to. If we don't kill them or release them, we have but one choice. Call them monsters and isolate them.... I’ve spoken to many predators over the years. They always exhibit amazement that we do not hunt them. And that when we capture them, we eventually let them go. Our attitude is a deliberate interference with Darwinism - an endangerment of our species.
