Risking a double post -
Additional thought because now I'm binging through the Origin series while puttering around the house -
On the topic of Zeon Deikun - I think it's the consensus of most people here that he was dangerously naive at best - a proto fascist at worst - But I do rather like his brief depiction in the Origin anime where he comes off as borderline deranged in his political rantings, and then immediately calms the hell down when he holds his daughter.
Combined with the depiction of the various 'disciples' of his philosophy as vicious, self serving, or self made miserable people who would have only reinforced his darkest thoughts, it really sells how an ideology becomes truly dangerous when it becomes divorced from basic humanity and empathy for others.
