Schizophrenics aren’t as dangerous as people with some other types of disorders. The trick is, especially with Paranoid Schizophrenics, that they don’t trust others so they don’t accept care. That’s why you see them disproportionately on the streets.

Psychopaths can also have psychotic delusions, but they aren’t paranoid like schizos. A psycho can accept help and it can even feed into his sense of entitlement and his delusions of dominating others, as if he manipulated the helpers. Psychos have a higher tolerance for being in an institution because they think of the other institutionalized people as prey.
