I had a relationship with a sociopath (officially diagnosed) for ten years. Sociopaths do not feel remorse, guilt, or shame for anything. Anything. They also don't care about contributing positively to the community or anything else, unless it is a direct benefit to them or makes them look good in some way. They have no empathy and cannot understand "feelings". A lot of people behave differently when drinking, myself included. It doesn't mean you're a sociopath, IMO.
