Mechanized Empalement

I have imagined a new type of execution, like impalement, but in the same style 
than guillotine. It use gravity force and when we place an person under the heavy
iron spear, like guillotine, it fall on posterior of executed people, but with a good position.

At the worse, if it don't kill them, we force by pressure to push on the iron spear until causing deadly damages on organs.

It can be found in Rumas republic and Poklemik republic. Other countries consider this as immoral and very offensive for body respect.
