You’re not wrong, but I think part of what Homestuck’s arguing is that what we think of as “true evil” IS just lack of maturity, and Bro’s stoic machismo is simply one of the different explorations of this stunted lack of emotional growth and self-awareness.
Caliborn isn’t just arbitrarily an infinite evil asshole–he’s literally biologically incapable of growth. AR is the same way–frozen in time developmentally by his nature as AI. Both reflect an absolute domination that echoes Yaldabaoth, and both turn out to be mayor components of LE.
The difference between them is that AR becomes LE through heroic sacrifice, having transcended his innate limitations through connections to others by becoming one with Equius and wanting to serve his friends.
Caliborn stunts himself willingly, by making the selfish and childish choice to murder his sister and force his predomination early. This is what allows him to play Sburb alone.
But it also secures his downfall, because by killing Calliope rather than devouring her soul through predomination, he puts Calliope’s soul out in the furthest ring, thus ensuring he’d be out looking for her as LE and causing the events that end his rule in Homestuck.
(This is why there’s no Caliborn ghost corresponding to Alt!Calliope’s timeline–she predominated naturally, and devoured Caliborn’s soul/consumed his strength. This is also why we don’t just see AR/Equius/Gamzee’s souls out in the void after they become part of LE–Caliborn didn’t just kill them to take over, he predominated and made their souls part of him.)
Both are tragic heroes, in the true Greek tragedy sense. AR’s story is one of heroic but flawed transcendence out of inherently unjust circumstances that made him innately imperfect–a result of Dirk’s own childhood hubris and demiurgic act of creation. Caliborn’s hubris is his own, and it’s what allows him to both create and destroy himself and the entire reality of Homestuck.
