Imagine being wrong about just one material fact and getting such an ego wound over it that you build a whole system to torture those who got it right by subjecting them to the world of their own conception which they didn't even make serious positive claims in favor of existing.
"Sure, my opponent made a logical and rigorous argument that I should have listened to and didn't for irrational reasons, but they had a brain disease that caused them to be wrong about more things than me. I will now prove I'm not mad or unreasonable by torturing them"
