I don't find that inconsistent. The Standford experiment showed that people act out the stereotypes of the roles they are assigned. My stereotype of a drill sergeant is yelling a lot, but fundamentally devoted to 'making unruly young boys into men' through bullying, disrespect - it seems to me that the conclusions predict that a quiet person who is assigned the role of a drill sergeant would suddenly start yelling a lot or a otherwise respectful person would become disrespectful. The stereotype of a prison guard is much different. Rather than 'unruly boys' it's 'hardened criminals' - the difference in reaction to being assigned a role can be explained by the differing stereotypes of the roles, as an alternative to the experimental conclusion being wrong.
