Memory altering machine

Memory altering machine I have heard stories of people who stutters getting into accidents and losing their memory because of that they also forgot their stutter, What if in the future they were able to alter or delete memories, like changing bad experiences into good experiences or straight up delete them from your memory I personally believe everyone will benefit from it from war veterans to domestic abuse victims, even pws, would you do it? If no, why not? Thank you for reading
