Or he was a soldier in war, doing what many soldiers do in battle when trained to do horrible things and unapologetically does horrible things. Comes back with PTSD about the horrible things they did and turns a new leaf with treatment. Sees they did horrible things because of the war machine and capitalism, wants to change the govt so the war machine and capitalism can burn.

Support those who can change and want change, burn down those who want status quo, status quo gets you Nazis and those on the other side who want strongly worded letters and small steps away from the right.
