Exactly, in the early years Doom often lamented that he barely knew his mother, that she died when he was just a baby. Later story telling has him older and older, and it messes with the myth of the idea of her being a perfect mother for him - she would never have had the time to show him her flaws, and he only remembers her love (see Triumph and Torment - 1989: Strange asks "Tell me, Doom, what do you remember of your mother?" he answers, "Only her face ... her smile ... her touch.") There was a certain romanticism to her being so much a mystery, yet he loves her to this day. Later books have eroded that mystery, that mystique, and I think it muddies the story of Doom's quest. Even in Books of Doom they make him older than in the origin story told in Marvel Superheroes #20 (1969):

and later still, in Infamous Iron Man #10 (2017), he's older still:

Yet through all of those stories, Werner is an even bigger mystery, barely discussed at all. Surely he had a bigger impact on who Doom was to become, and whose death he would avenge.
Werner was at times the moral North Star for Doom. But Werner was unable to protect the Zefiro from the malevolent forces that plagued them, so Victor - who saw power as the way to freedom - always faulted his father for that shortcoming.
Books of Doom takes on some of these themes, but I agree that Doom rising up from the dirt and taking power by his own will and cunning is far more interesting and compelling than having royalty bequeathed onto him by birthright.
