yes primarch minds are conditioned beyond anything we can comprehend and in terms of raw intellect their I.Q's were probably well over 200.

when it comes to violence though, this is something no human ever has to be taught. violence is a primordial part of our genetic code, it's instinctual, as is the sex drive. now astartes never seem to be bothered about sex so it seems to me that all of the primordial energy from the instinct for procreation is redirected towards violence, making their violence all the more violent.

as for mental power and self control, absolutely they have power the likes of which we will never know but self control? yeah there are one or two who are stalwarts of self control but there is evidence on most of the primarchs totally losing control at one time or another, because as powerful and as conditioned as they were every one of them was still subject to their emotions (which are also on the instinctual level), which can, and has, overwhelmed their self control.

i would agree that the emperor's emotions have been eroded by time. this would lead to him having no clue about the emotional states of his 'sons', and because primarchs physically matured so quickly and were raised by themselves or by people who were their mental inferiors, in my humble opinion i would regard most primarchs as being emotionally juvenile.
