I would ask you to support your claims with evidence.

1. In several instances it is mentioned in the HH books, that Space Marine fought Space Marine, <the whole raison d' etre of the Space Wolves was to fight everybody, including Space Marines and Russ specificcally states that they have done that before.

2. Unlikely that Legions were folded into others as Legions had singular ways of going about things and moral codes, ethics and the likes.Just switching Neophytes between Legions caused friction (see Scars).

The Fact that Guilliman did not pen his Codex Astartes until after the Heresy, when the 2 Legions were already wiped from the Imperium for decades (wiped before Corax was found as we see in deliverance lost), is even more telling, as that book is the only unifying codex of strategies that was then taken in by almost all chapters. Even those that don't follow it will have heard of it.

3. Astartes were a tool of war, brutality was their trade. If Conrad Kurze butchered a couple of thousand people to not have to go and subjugate several  planets, destroy the infrastructure and so on, that was in the will of the Emperor. Let them surrender and be subject to antiproportional warfare instead of getting a costly prolonged conflict that necessitates rebuilding afterwards.

Jagathai stayed incommunicado, yes, but he also followed orders and was in campaigns or n his own but pushing the borders of the Imperium...

4. I suggest you read the first novel of the HH series, especially the part were Abbaddon makes a case for killing of the interex (a human civilisation) because they are lenient in their dealing with xenos, as Empi has said that the Galaxy belongs to humans and that making it safe for them is the task of the astartes, aka xenocide.

5. as for mutations: To use "Fear to tread" when Sanguinius tells Horus about the Black Rage and Red Thirst: "You know the reason! [...] I will not be responsible for the erasure of the Blood Angels from Imperial history. I will not have a third empty plinth beneath the roof of the Hegemon as my Legion’s only memorial!" .....

Empi was more lenient when it came to gene mutation of Space marines, though the thousand sons killed themselves and the Emperor's Children died to the blight both ended with the discovery of their respective primarchs,

6. Codex Ultramarines 2nd Edition states that all 20 Primarchs were found and fought in the Great Crusade, Unremembered Empire states that the 2 missing Primarchs were known to several of their brothers, like Guilliman and the Lion, to qute "Vulcan Lives" "I am [troubled] Artellus. Very much so. None of us wants another sanction, another empty pillar in the great investiary, another brother's name excised from all record. It is shame enough to bear the grief for two. I have no wish to add to it, but what choice do I have?

7. Curze was the arbitrtor/judge, not the psycho killer... and Angron: the Nails were not in Empi's plan, nobody knows his function or role. As for "roles" even little Fulgrim, who was more an administrator and did not fight, could do that naturally... doubteable that 2 other primarchs would not be able to do it. All that we know of all primarchs points to innate skills at warfare and violence.

8. Mindblasting from existence: Empi did that before, with Horus being around actually see "the wolf of ash and fire" in  the Eyes of Terra anthology

9. Nikea was an idea of several primarchs (Mortation and Perturabo and Russ (ironic)) whilst Magnus,Sangiuinius and Jagathai liked the Librarius. Being a psykr was not forbidden, some actions, like summoning demons  was...
