One thing I don't get with blood angels and the red thirst is how did everyone just forget that it existed?
They were called the The Revenant Legion before they met sanguinius and I'm pretty sure it's implied that the other chapters all keep their distance because of how bloodthirsty and violent they were.
And like you wouldn't forget the time you watched one of them drain a serf dry of blood and rip out the throat of another.
Like your gonna remember that.
So I like to imagine a scene where sanguinius decides to come clean to all of his brothers and they all already know XD
Blood angels all in the corner being like bye dad we love you ╥﹏╥
Sanguinius: thank you for meeting me brothers and father. I can hide the truth no longer. I have a truly evil secret that I have been hiding all this time. A shameful dark secret that may very well make you think me and my legion monsters I-
Big E: Is this about the vampire corpse eating thing?
Roboute: Do u mean that weird trance where they go into a rage and bite everyone? Yeah if you could try and get that under control brother I'd appreciate it. :/
Dorn: i sanctioned them after the Second Siege of Yarant. They ate prisoners in front of the enemy.
Fulgrim: Yes I remember. They would walk around with gore and blood all through their hair and armor. Absolutely ghastly! They smelt worse then Cruze and the death guard put together! Really brother I don't know HOW you were able to turn them around.
Big E: Well anyway son hopefully you get that sorted out because I'm pretty sure Malcador would force me to sleep on the couch if I got rid of another legion HAHAHA XD
