Charlie is compassionate and empathetic to a fault, feeling genuinely upset at the idea of harm coming to others. Although she isn't unaware that Hell is populated with souls that have committed egregious acts in their living lives, she still views their yearly extermination as a senseless waste and makes it her personal mission to help them avoid it via self-betterment and eventual redemption, something she is seemingly alone in believing is possible.

Voice Wise, I'm actually looking for more of Jill Harris' Charlie. (The one from the pilot)
