Changes

The Cabal believed that, after the Heresy, a scintilla of the honourable being he once was would remain within Horus, eating at him and fueling a self-destructive sense of self-hatred and loathing that would see Horus fall on his subjects in an acceleration of the violence of the Heresy, creating civil strife amongst the traitor and Chaotic forces that would culminate in a final armageddon. The end result of Horus leading humanity would be total extermination of the human species within two or three generations...however, if this were so, the powers of Chaos, so heavily invested in humanity, would be extinguished with it.
