Persons who refuse to acknowledge their own shortcomings tend to have personalities that are shrewd and combative. How come? mainly due to the fact that one of the ways to circumvent the sensation of guilt is to provide a justification for the error, which may appear to be rational, but in reality, it is nothing more than a means of avoiding acknowledging the error and, consequently, the sensation of guilt.
My research has shown that individuals who become intoxicated as a result of using alcohol, smoking, or drugs are more likely to exhibit the effects of a guilt-free condition. To put it another way, people get drunk for the sole purpose of removing the feel of guilt that is associated with anything. More intoxication (alcohol + cigarette etc) results in a greater sense of freedom from guilt, and as a result, one is considered to be in a high condition. At this point, people have either forgotten the origin of the guilt or they have found the justification to completely get rid of the guilt.
