I had this thought when thinking over the morality of the primarchs

But then i began looking at each and every primarch. Aren't they rather evil for allowing the emperor to continue as he was without starting an actual debate on the matter of how the men and women were treated in the imperium? having innocents destroyed to fuel the imperial war machine that went on to genocide the entire galaxy.

Like take Guilliman and Russ for example. Angry with Angron that he chose to stand against the emperor than continue as a slave. A slave to the imperial war machine that is fueled by the life destroying labour inflicted on uncountable innocents. Aswell as those billions of people being forced into millitary service with no choice in the matter, torn away from their families, sent to go die on some distant battlefield a day a week a month later. The injustice of it all never going answered as the primarchs turn a blind eye to it as they turn a blind eye to every horror befalling people of the imperium. Even someone like Vulkan is part in this hypocrisy. Now if they all viewed themselves as tools meant for a job and removed all emotion from the equation like they're robots i wouldn't be making this argument. But they are very clearly so human in their emotions and actions. They willingly followed the greatest tyrant in existence and cared not for the common man. If Vulkan and his sons were half as good as they pretend to be, they wouldn't stand for the treatment of humanity.

The primarchs decided to stand with the emperor and furthered his vision for the galaxy, expanding his tyrannical rule throughout the stars blind and deaf to humanity's suffering.

None of them are exempt, all of them are guilty.

Thanks for coming to my morality post, i had a blast writing this ^^
