One article I saw quoted the aircraft value at between $6 and $10 million. Given a significant portion of that would be the four PW4000 engines and readily salvageable avionics, I think it's safe to say this airframe's future is beer cans. Especially since Delta has ready 'spares'.
As to the actions of the aircrew, hindsight is always 20-20. I'll wait until I see some sort of official report before I condemn their actions.
