Liposuction for the mind?

I don’t know about you but I think this is probably a step too far (Brain researchers open door to editing memory). Aside from the dangers of loosing material around the edges there are wider ethical issues. Are you still responsible for actions of which you have no memory? What are the implications for emotional resilience if I can just edit out the bad stuff? A few minutes thought on the implications for criminal activity and a myriad of fairly nasty implications come to mind (maybe I’d like to forget some of those for that matter). What about guilt? Now I don’t want to dwell on that but a brain swept of guilt does not a good person make. It all takes cosmetic surgery to new depths. Nip and Tuck adds chemical lobotomies?
