Tieflings aren't hellspawn - that's a racial slur.
Yes they are hellspawn. Also they are now a homogenous race of their own unlike before, so yes they are even more definitely hellspawn then before.
Also I just fell of my chair laughing.
Imagine this situation:
You die and end up going to hell where you are destined to eternally toil under an opressive regime of archdevils in an eternal torturous war against demons and constant plotting and one-upmanship amongst fiends.
BUT at least you are not racist.
HAHAHAHAHAHAHA, shit man, that's the hill you're going to die on? Okay xD
