Thats a real definition of sociopath you've posted there!
here's a more basic one i found:
a person whose behavior is antisocial and who lacks a sense of moral responsibility or social conscience.
So yeah drunk or sober the alcoholic at the very least displays characteristics of a sociopath...they can change if they get face to face help, are willing and ready to go to any lengths to change and do what is suggested by whoever is trying to help them!
The guilt and remourse felt by an alcoholic is all self centered...so is that really guilt and remourse?! I don't think it is the same as most non-alcoholics experience those emotions...e.g. non-alcoholic may feel guilty for an action and then look to rectify it, alcoholics feel the guilt but generally apportion blame elsewhere...just my experience:-)
