Cognitive dissonance
I find it quite ironic, that infernalists basically admit that 99.99 % of mankind will burn in hell eternally, but they always make an exception for themselves, their friends and their family. Every infernalist is a universalist when it comes to their family. But if they were consistent, then they should view themselves, their family and friends as damned, created and predestined for eternal torment as they are not living saints thus won't make it to heaven.
Very interesting.
