ELI5: Why do the voices in schizophrenics' heads say negative things?

I've always read about schizophrenics having voices in their heads talk to them, telling them to kill people or to kill themselves. Why don't these voices say more positive things?

Typically Schizophrenics are diagnosed BECAUSE of the voices being constantly negative. there are plenty of people that "hear voices" that are mundane or even positive. What sets Schizo's aside from the rest is theirs are constantly negative, or they choose to listen harder to the negative, or the negative is stronger due to some traumatic event.

In any case, its not the Schizo that makes the negative thoughts, its the negative thoughts that put forth the diagnosis of Schizophrenia.
