Have you met inmates such as Nana or Jennifer Shibuya? [honestly, he still can't figure out why they are considered criminals :|] They wouldn't hurt a fly or do anything that could be considered malicious.
As someone in charge of a considerable amount of population, Acumen should realize that it's warped and biased sense of justice will only lead to undesirable results. It should relinquish it's status as the warden and give the power to someone much capable than it is.
