Mind Wipes

Apparently there is a new method to prevent people from remembering stressful events and having PTSD afterwards. I find this troubling coming as it does after doctors have found a way to remove painful memories. After all if the concentration camp guards can't remember shoving people into ovens, and shooting the children, how can we ethically punish them? What if we can't remember it even happening? Imagine this technology gradually perfected. The government could commit any horror and make the public forget. This is a slippery slope at the bottom of which is the annihilation of nothing less than the human soul. People need their pain, their fear, their guilt and trauma. Otherwise they aren't people any more.
