Is it possible to cause people to age super fast?
If so, It would be good to take murderers and just hyper-age them to a biological age of say 75 or 80 and then release them to the public.

Most people of that biological age are too weak, too short of breath , too frail, too lacking in explosive muscle power to rape or abduct or murder anyone.
Sure maybe you might think you could do the same by severing their spinal nerves and leaving them in a wheel chair, but those wheelchair basketballers are still pretty strong and could definitely murder a girl if they got close enough to grab.
And paralysing them from the neck down would cost too much to look after them.

With hyper aging they would die off pretty quickly and they could look after themselves for a while before they died.

Obviously killing murderers is best of all but since the death penalty is going away , disabling murderers and rapists and making them too weak to commit the crime again is the next best thing.
And desu death isn’t a worthy punishment for rape of an adult , even violent rape, but disabling or enfeebling is a good punishment and saves on costs in looking after them in prison
