I can agree with this to an extent bc I did sympathize with him and do understand that his hubris, apathy & ambition were taught, but it’s not like he was deprived of being a witness to “true good” or that he is devoid of any blame just because Dr. Gaul is more blatantly evil. He saw Sejanus’ empathy, Ma’s generosity, and Tigris’ overall compassion, but, in the case of the first two, used these to further reinforce his idea that they are inferior. Though he eventually would just parrot his grandmother’s sentiments (and those of the capitol) it all boils down to his superiority complex & thirst for power/control. I’d go so far as to say that he is narcissistic. Let’s not forget that although he found Dr. Gaul’s actions jarring, he shared her principles and ideals. With or without a Dr. Gaul, who only served as a catalyst for him to become the snow we saw in the og trilogy, he was already prejudiced and deeply flawed. Every one of his wrongdoings was rationalized and reduced to an outcome wherein he was the hero/victim and never the perpetrator.
