explain your argument behind point 3 because I do not really see any argument you could make.

Horus side did not really give much of a damn about psykers (aside from the Word bearers and those generally made do with chaos worship and gained boons and were not psykers by default), at least not the Death Guard or World Eaters, whilst the loyalist Scars and Wolves never got rid of their respective Librariums. After Calth the Smurfs reactivated it, the Dark Angels went active during the campign against the night lords. .....

4.Magnus was loyal to begin with, he wanted to wan Emps of Horus, that was the dilemma of the whole story.

Horus sent Russ as sanction, whilst Emps only wanted Magnus brought to Terra....
