Best advice is to find a frame builder or experienced shop to provide their opinion after hands-on evaluation.
My opinion is that this has "repair" potential, but would never be a frame to trust in critical moments. From the pictures, the bend seems to have allowed the seat stay to remain cylindrical, rather than collapsing or creasing the tube wall. That would give me hope that a gentle and careful repair could be effectuated.
EDIT:
You should also be concerned with damage at the seat cluster, dropout, and bottom bracket. It isn't possible to change the length of the side of a triangle without also changing the angles that the sides meet.
