Alright, this is somewhat of a setting question as well. Anyway, in this world I'm writing humanity has been united by the UN which now controls an "empire" which controls several planets in the Milky Way, and the official ideology is one of laissez faire capitalism, globalism, imperialism (against humans and primitive aliens), individualism, and social darwinism (the cultural imperative for the strong to surive and breed, and the poor and weak to die so that the species as a whole can progress). My story concerns veterans of a war between humanity (under the UN) and a horde of technologically advanced alien refugees. Humanity won and wiped out the refugees, but at a huge cost: hubdreds of millions died in the fighting, econmy in tatters, and whole systems destablized or abandoned. Anyway, one of my characters is a former member of the Peacekeepers, the elite, highly trained military force of the UN, and he is also from the illustrious and powerful Dangote family. As one might expect from someone of his background, prior to the war he was a great beleiver in ideals of the UN. But in my story he is a deserter, and I want to have him slowly begin to abandon UN ideals, to become an intellecual dissident. The problem is, I'm having a hard time thinking of an event or series of events which might change the mind of someone so devoted to such a beleif system. I thought maybe he could lose his faith when a bunch of his men are abandoned by the UN, or if their lives are sacrificed needlessly or callously, but wouldn't the death of his lessers simply reinforce his social darwinist beleifs because the died so their betters could live? Besides, wouldn't such a backstory be cliche? Another thing I maybe thought about could be that he either loses faith in the idea of human evolutionary superiority due to the heavy loses the Aliens inflict of the humans. But since humanity won, wouldn't that also reinforce his old beleifs? And what kind of radical should he become? He would be aware of Marxism and Facism, as he was very well educated, but those philosophies are considered outdated in the current setting. Is there some way one could interpret evolutionary theory to reach a different type of ideology?
