Why does the Chaos gods love Abaddon but hate be'lako?
Be'lakor gained his power by playing the chaos gods against each other, playing off their egos and need to one up eatchother to basically say, "hey if your really so much better than that guy you should give me more power than he did to prove it."
Isn't that exactly what Abaddon is doing? I'll admit I'm not big on black legion lore, and I know he sees chaos as a tool to be used and mastered insteadof worshipped, but isn't he still basically doing exactly what caused Be'lakor to lose his favor with the big 4?
