Burning, as in common cremation, turns someone to ash with some components that are not fully reduced. Vitrification homogenizes them even further.
But the point is also to take them out of the ecological cycle. The material of scattered ashes are processed by the ecology and eventually are reintegrated into larger and larger life forms again. By reducing a tyrant to a solid and locking them in a vault, their material is removed from the life cycle for as close to eternity as we can fathom.
Now if we had the option of throwing them into the sun, that would nicely reduce them to plasma, but that involves a heavy duty launch vehicle like the Atlas V. (My dad did the calculation once, and that would get about 150 lbs into the sun. Escaping earth is expensive.)
