Hell has to exist. Otherwise that means I'll never own a 3 headed dog.As we have no reason to believe that hell exists (no wait, I'm sure "Doc" will swoop in with some clickbait crap) the temperature is whatever you want it to be.
IT is also only IT if you want it to be.
Haven't you ever read Dante's Inferno?
Hell has nine levels, and as you descend each level is progressively colder than the one above.
I think level 9 is about the same temperature as our dear Tyrant's pitiful excuse for a heart.
