Please read each of the Codexes. All of the Primarchs were tainted by Chaos during their transportation through the Warp, and the Ecclesiarchy now teaches that the 9 Traitor Primarchs fell to Chaos as a result of this taint. Whether the Emperor knew or didn't know has not been addressed, though the Emperor's willful blindness where the Primarchs were concerned has been addressed multiple times in the Horus Heresy novels. One could argue that the sentence you highlighted is an overstatement, I will review it. But from the pon t of view of the 41st Millennium, no one would argue with it.
