I have seen various forms of 'scales of consciousness', however, I don't usually agree with their definitions 100%.
Guilt is a form of unconsciousness, it is ultimately anti-consciousness and does not have an intention of releasing the pressure on our will and emotionality. Our conscious parts need to understand that guilt has us constricted and to make conscious changes in self such that guilt can be cleared from our emotional field.
Guilt is a kind of replacement for emotion, plus a limiter and even attacker of emotion - hence the numbness.
There are aspects to it that make it appear to be like an emotion, but one key understanding that makes the situation clearer is that guilt cannot move on its own - unlike real emotions.
