Is Leandros right? Is Guilliman corrupted by Chaos?

>Thinking the Spiritual Liege can be corrupted
Trying to sow seeds of doubt, heretic?

Yes and no. It's a good rule of thumb for regular people and Astartes, but exceptional individuals can rape the warp and still have shiny golden cocks. See most of the Grey Knights.

Didn't the Emperor got his powers and made the Primarchs based on a deal, which he violated, he made with the Chaos Gods? The whole Imperium is the result of the Emperor thinking he could make a faustian deal, con some eldritch abominations, and get away unscathed.

>Spiritual Liege
That's Calgar.
Not Guilliman

Leandros is a chump Codex-bumper and Guilliman would be ashamed of him.

The Emperor's powers and intelligence come from the fact that he is many powerful souls made one. What fluff we have on the matter (very old fluff mind you) says that the during the beginning of mankind's history, psyker souls were being devoured by the chaos gods so mankind could not protect itself from the forces of chaos. So many of the world's psykers got together and killed themselves en masse. The huge torrent of souls was too great to be destroyed, so instead of passing on, they merged their souls into one of great power and reincarnated themselves as the being we know as the God Emperor.

true but supposedly that lore was retconned and now we just don't know.

>Believing the same bullshit that drove Horus to Chaos
Come to the side of Law.

According to Black Library. But Black Library is run by chaosfags, and their chief editor wrote Mortarion's Heart, the interview for which, he said he retconned the event because it offended his chaos fanboy sensibilities.

They literally cannot be trusted, because they literally retcon the setting based on their own personal preferences.
