I feel that sin and evil are the negative part of you, and I think it’s like a battery: you’ve got to have the negative and the positive in order to be a complete person.

Parton frames moral struggle in practical, human terms rather than as a purely theological verdict. By likening “sin and evil” to a battery’s negative pole, she suggests that what we fear or condemn in ourselves can function as a necessary counterforce—something that gives shape, tension, and energy to the “positive” parts of character. The image implies wholeness comes from acknowledging inner contradictions instead of denying them. It also hints at a folk-psychological ethic common in Parton’s public persona: humility about human imperfection, coupled with an insistence that people can still be fundamentally good and capable of growth.
