Capital punishment is usually carried out by lethal injection. It comprises 3 parts. One to put them to sleep, one to paralyse them and the last potassium to stop the heart. A point to note is that death by lethal injection destroys organs. Death by hanging, on the other hand, leaves the organs in perfect condition as the person dies because they break their neck.
There are issues of cruelty on both counts, however, for the point of this post, I won’t go into the morality. I am taking the fact that people awarded capital punishment deserve it and all they get, as fact.
I feel that if someone has commit a crime so heinous as to deserve capital punishment, than the least that the person can do is automatically give back to the community by “donating” their organs.
