Sociopaths have no conscience and therefore they care not about anyone or anything. They can destroy damage harm and feel absolutely NOTHING.
Can they be made? An injection or a pill that would turn an ordinary normal everyday typical person into a killing machine? Maybe "they're" already working on it for the upcoming Armageddon that is sure to happen soon. Maybe they already have it and have tested it and it works! Maybe they haven't. In a certain period of time we will find out. Everyone says so.
