Optional Writing Prompt #5

Imagine this: using newly discovered scientific methods, governments have gained the ability to wipe out all the memories of the worst criminals. Do you think that this would be a just punishment for some crimes? Do you think these criminals could be released back into society after their memories are wiped? Do you think people who commit crimes do it because of what they've experienced in life or because of who they are? Would wiping their memories restore them to being cooperative citizens?
