[Aliens] Private Hudson. What exactly is "wrong" with him or what motivates this particular soldier?
gpt
Hudson had several issues.  He was a competent soldier and knew his job, but he was used to an orderly chain of command with him at the bottom.  He liked to buck command and give people shit, probably because, like a lot of bullies and troublemakers, he was somewhat insecure in his own abilities.  It's easier to mock others than to put yourself in a position where others can mock you.  Also, he had what is known as "short-timer's disease".

His tour of duty must've been mostly one-sided affairs where the Marines faced no real opposition.  They rolled in, looked tough, and kicked ass.  He never had to take real responsibility, just following orders and being a smartass while doing it.  He didn't have to learn self-reliance or how to take command.  When faced with the desperate situation at the colony, he didn't have the experience of handling true crises to draw on.

It was also his last month in the Marines.  His head wasn't in the game.  He had one foot out the door and was already dreaming of his life as a civilian.  Facing death when he was so close to getting out made him somewhat hysterical.
