The question is when now the tail hits and the stabilizer separates: Will the now tailless wing's negative pitching moment overpower the nose-up pitching moment of the engine thrust? If so, the result would be a quick nosedive into the ground, consistent with the destruction we see. If not, we would get a stall and then a nosedive somewhat later. Which one happened here?
In a normal flight attitude as A4 pointed out the Nose-Down would be massive and immediate.
In a very Nose- Up attitude, the Nose- Down pitching could be somewhat delayed and reduced at the beginning (due to shift of Center of Thrust + momentum vs. Center of Drag/Lift), then increasing while the Nose is lowering
