Leman Russ is not at fault for attacking Magnus the Red, his Thousand Sons and turning Prospero to ash. The Primarch of the Space Wolves is the Emperor's Executioners and was sent to destroy the wayward, Sorcerious Thousand Sons by the Master of Humanity. Horus mastered this from behind the scenes and manipluated a majority of what transpired. It is wrong to blame the messenger for doing is appointed duty, it isn't fair to shoot Leman Russ for the delivery of the Emperor's message to a Primarch who broke the Council of Nikea.

None of the Primarchs whom broke faith and swore due diligence to the Ruinous Powers cannot be redeemed and return to the fold, but Alpharius/ Omegon did not swear allegiance to the Chaos Powers and their path, though outwardly looks traitorious, has a part to play in the saving of the Empire of Mankind 10K years later. So, if there is a decent number of Alpha Legion left that are uncorrupted, their presence and path since the Seige of Terra may play a role in survival of the Imperium.

Perhaps the Emperor is hedging his bets and playing both sides. Not much difference between Chaos and mutations, especially when you have Primarchs, Legions and Chapters hiding genetic flaws and mutations from the Empire's Administration and the Inquisition.
