Trully I think that Sanguinious would have been corrupted by chaos under similar circumstances. Horus was not even remotely disloyal to the Emperor before the Heresy and was reputed to be the most loyal primarch of them all. The greatest and most favored of the Emperor's sons, Horus would have never bretrayed his father under almost any circumstance. It took the Word Bearer's scheming, A Nurgle Demon Weapon, A chaos temple, and all the influence of the Chaos Gods undivided to corrupt Horus. He was even in a hallucinogenic haze when they dug real deep to find the smallest speck of jealousy. I hardly think Sanguinous would have stood a better chance against a mental assualt like that.

I do not doubt at all that the chaos gods could devise a similar fate for Sanguinious if he was the warmaster. It would take different methods to corrupt him but he is not immune to Chaos.
