[Warhammer 40k] Why was the Emperor such a terrible father?

The Emperor was supposed to be the most brilliant and powerful human to ever live. He single-handedly created the Imperium and one of the most powerful military forces in the galaxy. The guy was for intents and purposes omnipotent and he obviously must've also been intelligent and wise enough to be able to manipulate mankind from behind the scenes for thousands of years.

So that being said, why was he such a shitty father? The guy's not a moron, yet it's clear even to the dumbest of humans that a lot of the Primarchs had major issues. I mean, when one of your children is called *Angron* and forces all of his soldiers to implant machines into their brains that torture themselves for the rest of time, isn't that kind of a sign that he may have issues that need to be sorted out? The same thing goes for guys like Konrad Curze, I mean when your kid literally becomes Batman *but also slaughters people without a conscience* that should set off warning sirens, right?

His reaction to Lorgar in particular was a clear sign that he had no idea how to handle being a father. Here's a kid that loves his father so much he literally reveres him as a living god, and what does Big E do? He obliterates Lorgar's hometown and forces Lorgar to kneel in front of him and Guilliman. Did it not occur to him that this might cause a bit of resentment that might bit him in the ass further down the road? Why was he so oblivious to all of this?

The Emperor was an excelent father. However, the Primarch's were never meant to be children. They were meant to be leaders of Mankind. Coddling them and doing everything for them kinda defeats the purpose...

As for their methods, he did object to some of them, Lorgar being the most glaring example. His approach was a bit heavy handed, but the Emperor had witnessed what Religion can cause, and really felt the need to try to nip that problem in the bud. 

Part of the problem stems from the fact that the Imperium, even during the Great Crusade, was colossal. Not even the Emperor could manage everything, and he HAD to give increasing amounts of leeway to the Primarchs. The more independent authority they had, the more their individual problems became manifest. 

Nikea was a perfect example of how the Emperor both understood what was happening within the Legions, and the root cause of it... It's also a prime example of the fact that he was quickly realising he had bit of more than he could chew, and that time was running out. His project became even more important, because he realised that micromanaging wasn't going to solve the problem, and he needed to cut the Legions off from their over-exposure to the warp. 

If i were to put it in a parenting analogy... It's like discovering your child has cancer. It's inoperable, so you resort to Chemo while you try to develop something that will cure it. Then you discover the Chemo isn't working, and you've got 6 months to figure out a cure or its game over.

The Emperor realised that micromanaging wasn't viable, and needed another solution. He couldn't coddle them either, because it wouldn't solve the underlying problems.
