I am not underestimating them in any way. they ight be the "sons of the emperor" yet for what purpose where they bred,  fighting war, creating the empire, bringing humanity under one rule. it was only that many centuries later, the surviving astartes and primarchs, through education programs would have been made fit to rule (iterators remembrancers and so on all on the expedition fleets, also there to educate the forces)

even if you put your ind to somehting, your ways of doing things are shaped by your previous experiences and your education. hence the simple truth that after a couple of centuries of warfare, you will not be the ideal civil ruler, human's  social behavior does not work that way,
