Unfortunately this doesn't quite work. I appreciate the suggestion, though. Healing is an exceptionally rare ability, and not something just anyone can pick up. Healers don't just get the ability to wave their hand at you and make your pain go away, to truly heal you they have to transfer your pain into themselves. They don't receive physical wounds, but it hurts them on the inside. In order to be a healer, you have to have a very self-destructive personality; someone who values other people's lives more than their own, and always puts others first, no matter what cost it brings to themselves. This character is an overall good person, sure, but they aren't that selfless. Almost nobody is. The other half doesn't work either, unfortunately, as "mass destruction" is a bit too high on the power scale. We aren't dealing with DBZ level battles or anything.
