"Christopher North" is an American composer, songwriter, and musician.

More Christopher North on Wikipedia.

He started hearing a voice which told him to smother another patient -- a friend of his -- with his pillow.

Basically he's been a terror in the community and a pussycat in custody.

I think he has serious difficulty controlling it.

It just shows that he's sort of out of contact with reality; his thinking is unrealistic, which raises questions about his judgment, problem-solving skills and how stable he is.
