What is the difference between the act of committing an act and the consummation of an act?

I - The act of committing an act is a brutal, imperious act that obeys an internal need that escapes the control of the individual and is experienced in a climate of tension that immediately subsides after the gesture is made.
II - The consummation of an act is a more complex and elaborate pathological behavior that follows a conscious scenario (although of unconscious determination) that is imposed on the individual as an impulse that is difficult, even impossible, to resist.
III - The act of committing an act is observed in some psychotic disorders, while the consummation of an act is observed in perverse pathologies, some repetitive behaviors of neurotic patients or borderline states, among others.
