I feel the neg human spirit can raise its vibration through love , light ,service to others around them , reconnection to source , cleansing , healing , faith and redemption in forgiving self and others , letting go of sadnesses , wounds and etc .It is interesting to consider if a demon can ever get redemption or become angelic . It would be nice to think so . But so far nothing I see , read , or hear leads me to believe that a demon has any chance but to be predatious and evil by nature. They may serve a specific purpose and being obedient become cleansed . What if their human host is capable of redeeming them too , that is a lovely thought .
