If you believe in re-incarnation then surely executing convicted murderers would mean they would be once again in our midst in next to no time?
But seriously folks there is no such thing as 'justice' because no matter what happens to the perpetrator
of a capital crime, nothing will put the soul - or that energy
which is the difference between 'living meat' and 'dead meat' - back into the victim again.
'A spirit is a soul without a body therefore a corpse is a body without a soul.' H.E. Manning.
