IMHO, the primary reason that the Army let him stay was because they felt they had too much time and resources invested in him (think all those years of college tuition they paid for him), plus they were short of clinical psychologists in the field. On paper, he was exactly what the Army needed; they felt a need to get out of him a minimum of when they put into him. Therefore, the system which usually weeds out bad apples was caught up in a self-perceived need to cultivate it’s fruit, no matter how poisonous said fruit might turn out to be.
