I’m not OP, but I can understand subtext so I’ll translate for you:

I’m not a religious person in fact I hate religion in general…

[…however, I understand that it is very common for established religions to have a character that represents pure evil…]

…but more and more I’m just starting to think this guy is evil incarnate…

[…lending validity to the idea that religious folk actually are right about something, specifically a person being “evil incarnate” existing among us…]

and it’s spreading across the world…

[…which is also a common trope in established religion that evil spreads and must be pushed back against]
