And you do understand that, as it breaks up, the different components, having a wide variety of mass/Cd ratios, will be spread over a large area, of which Point Nomo is the centre? It won't conveniently land in one lump, hence maximise the chances of hitting no-one (or Nemo).
Actually there are lots of choices.
1) Let if drift off into space.
2) Hit it with a missile and let all the little pieces disintegrate in the atmosphere.
3) Detonate it with a bomb and let all the pieces disintegrate in the atmosphere.
4) Leave it where it is in orbit.
