A better way to put it might be that Nick does care about being seen as a cuck, but his coping mechanism of lying to himself and calling everyone who doesn't partake in the Qouple lifestyle "Scandinavian incel prudes" allows his brain to resolve that cognitive dissonance somewhat neatly. So Total Aaron Death takes a whole lot of precedence over dealing with the trifling thoughts of Dear John and Jane Sneed, who he narcissistically portrays as lower-order organisms.
I agree, and people need to slow down. Aaron is a total nigger, but he is a whole lot better than Nick. He doesn't have a personality disorder as strong as Nick's NPD for one, so even though he's a cunt he could be helped out of his retarded predicament if he wised up.
Aaron wasn't trying to establish a Qult, Aaron wasn't turning April into a crackhead (it was the opposite, in fact). Aaron is just a normal man with shit personality traits like hedonism, impulsiveness, selfishness - not everything has to be irredeemably clinical.
