Mutation is a positive force in evolution because it introduces new genetic variation, which can be acted upon by natural selection. Without mutation, there would be no source of new genetic variation in a population and evolution would not be possible. While some mutations may be deleterious, others may be beneficial and increase an individual's chances of survival and reproduction.
