More to the point, in Terry's case, we don't know. It is possible, that without schizophrenia, he would never have been racist. (At least if we define "racism" in terms of explicit statements/actions, as opposed to unconscious biases.) It is possible that he always was racist, and would have been even without schizophrenia, but schizophrenia took away his ability to hide it from others, or made him not care about doing that. Nobody can really know.
