[01:58] <[Abaddon]> I figured out why my guy went traitor
[01:59] <[Abaddon]> There are a myriad of reasons. Freedom, autonomy. Feelings of berayl and injustice. Revenge. Or more petty things, like greed, hatred.
[01:59] <[Abaddon]> Or corruption within by the failings of others.
[02:00] <[Abaddon]> But, no.
[02:00] <[Abaddon]> He was on his way to joining the Death Company. The Sanguinary Priests and Chaplains did nothing (could do nothing) to stop it or slow its passing.
[02:01] <[Abaddon]> All his adoration of Sanguinius turned to ash when he was burdened with suffering the primarch's maddening agony. His fears, regrets,  his failings. His death.
[02:01] <[Abaddon]> Over and over again.
[02:01] <[Abaddon]> And the Emperor who did nothing to stop it.
[02:02] <[Abaddon]> Sanguinius was the best of them; if Horus had not been Warmaster (out of favoritism!), it would have been been him.
[02:02] <[Abaddon]> If Sanguinius had fallen to Chaos along with Horus, it was Horus who was terrified at the idea of his best friend becoming his greatest enemy.
[02:03] <[Abaddon]> And this hero of mankind was thrown away for the sake of a worthless corpse.
[02:03] <[Abaddon]> The emperor expended him as a way to weaken Horus for the killing blow (his rationale, not the actual truth)
[02:03] <[Abaddon]> But more importantly, it was BOTH of their weakness that lead to him being cursed with Black Rage
[02:04] <[Abaddon]> He hates them both
[02:04] <[Abaddon]> Sins of the Father and all of that
