A pedophile is a very specific thing. It's someone who is sexually aroused by underage children. More specifically, it's someone who acts on those desires.
that's it. That's the end. There are no other possible ways to get into that club.
If someone goes to lunch with a pedophile, knowing they're a pedophile, to try and get $60,000, they're morally corrupt. They're a shitty person. But until they start abusing these underage girls, they're not pedophiles themselves.
This is not a hard concept. There are 5 categories of people who went to that island.
1. unaware of his predilections
2. aware, and morally corrupt
3. pedophiles who were unaware of his predilections
4. pedophiles who were AWARE of his predilections
5. pedophiles who went to have sex with underage children.
The argument here is that the only reason you would ever go to that island is if you were 5. This is unreasonable, and it makes you kind of dumb.
