Question comes as a kind of addition to one I asked awhile back. It was about having met a truly evil person. I can tell the story again if anyone is interested but as a young teen I interacted with a guy in the Aryan brotherhood from California several times.
They served overseas, and I know they’ve killed multiple people. I didn’t ask for more details.
Good on ya for respecting the gravity of it and his silence about it. It’s fucking horrible what war does to people. You could sign a contract with the best of intentions, naive as they may be. Regardless of why you joined, they have your ass, and whatever you’re forced into will weigh on you.
