A more thoroughly worthless NCO I cannot imagine. Glad to take the Army's money, wasn't he? But he was never adult enough to consider what he had signed up for, what he might have to do.
Like so many other children in uniform, Mejia figured he could count on never having to go to war.
Idolize this character if you want; it says more about the maturity of your own outlook than anything else.
By the way, as an NCO, Mejia was responsible for looking after the welfare of his soldiers. But he ran out on them, didn't he?
Yes, Mejia is the perfect hero for the childish and irresponsible. You're welcome to him.
