The ship told you a guilty system recognises no innocents. I'd say it does. It recognises the innocence of a young child, for example, and you saw how they treated that. In a sense it even recognises the "sanctity" of the body… but only to violate it. Once again, Gurgeh, it all boils down to ownership, possession; about taking and having.
The quote from Iain M. Banks' "The Player of Games" reflects on the nature of guilt and innocence within a flawed system. It suggests that while a guilty system might not recognize true innocence, notably that of a child, it still acknowledges certain vulnerabilities, like the sanctity of the body. However, this recognition is paradoxically intertwined with the intent to violate that very sanctity.
