i think the general consensus of the regulars to this wiki is simply that because of emps' intellect he couldn't relate to any other being, even the primarchs would be as children, intellectually speaking, compared to emps.

if emps had actually raised them himself they may have matured very differently, but since they were mostly raised by 'mere' humans then they matured among all the pettyness, vindictiveness, jealousy, etc, that normal humans experience. if emps had raised them these small minded emotions may have been absent in their upbringing resulting in far more stable personalities. but because emps couldn't emotionally or intellectually relate to anyone then such emotions in the primarchs would probably have him thinking "they'll grow out of it, how can they not? I created them." remember that amongst his attributes emps was monumentally arrogant, and couldn't concieve that he would fail in his endeavours, including the primarchs.
