How can you deal with a schizophrenic?

Difficult: Do not expect any real warmth from the person; if they can still express it, that's good. If one is a family member, make sure the other family members do not buy into their insanity or think it is spiritual. Any signs of violence, get away by whatever means. Remain caregiver only if you can handle a difficult, thankless and sometimes dangerous task. Require they accept medication. Good luck.
