Can any blood angels fall anyway without falling to the black rage anyway? Because i always see the line that the fate of every blood angel no matter what is the black rage because it is inevitable. I never heard of or seen any official chaos corrupted blood angels anywhere. I mean the closest is when they trick Rafen actually blood brother that he was sanguinius reborn. But not actually falling to chaos. So can they or they can’t because of their gene flaws?
