It won't deblur, it will blur. If you subtract two of them, you do a Laplacian of Gaussian or Difference of Gaussian filter (DOG filter), and that can locate edges. If you add a scaled version of the DOG image to the original, it can "enhance" or emphasize the edges, which you might consider as a deblurred version.
