I (Primarch, M~200s) was once the most loyal son and even favorite, of my father, the Emperor of Mankind. He raised me, gave me command of the greatest armies in the galaxy, and proclaimed me Warmaster. For a while, I thought we were on the same page-conquering the stars, reuniting humanity, and making a better future for all. But then, I started to notice things... First off, my father started acting distant. He left me to handle the Great Crusade while he locked himself away on Terra, refusing to explain to ME what he was working on. Meanwhile, I started hearing rumors-whispers that he planned to discard us Primarchs once we had outlived our usefulness, just like the Legio Cataegis (Thunder Warriors). Turns out, he didn't even see us as his sons, just tools. I wanted to confront him on my concerns but he has isolated himself on Terra to toil in his "Great Work". He even brought Rogal with him but not ME back to Terra! Then I learned about Chaos. At first, I thought the Warp was just a turbulent sea (idk I wasn't really listening to Magnus explain it to me), full of warp-xenos and such. But the Chaos Gods showed me a vision of the future on Davin, one where my father ascends to godhood, enslaves humanity under his rule, throws us aside, and abandoning everything we fought for. They offered me another path: true freedom for mankind, free from his tyranny. So, I made my choice. I rallied my brothers, the ones who saw through his lies, and declared war on the Imperium. Of course, not everyone agreed, some of my brothers and my OWN sons betrayed me. Like Fulgrim was FORCED to kill Ferrus. Crazy right? Choosing the Emperor over their Warmaster. They act like I'm the bad guy, but I was the one trying to free them from a father/Emperor who never truly cared. I truly believed that Ferrus could be convinced of the Emperors' tyranny, but I guess not. We'll see if my favorite brother, Sanguinius can be convinced at Signus. Now, the galaxy burns, my brothers are divided, and I have to deal with the consequences of my decision. Some say I've doomed humanity to be enslaved by the Chaos gods, but I still believe I did the right thing! I mean, I never wanted to unleash my legions!

So Reddit, AITA for rebelling against my father?
