In terms of aggressive behaviours, one could imagine a continuum between Active Aggression (which includes violence & brutality) and Passive Aggression. Passive-aggressive behaviour refers to passive, sometimes obstructionist resistance to authoritative instructions in interpersonal or occupational situations. Sometimes a method of dealing with stress or frustration, it results in the person attacking other people in subtle, indirect, and seemingly passive ways. It can manifest itself as resentment, stubbornness, procrastination, sullenness, or intentional failure at doing requested tasks. For example, someone who is passive-aggressive might take so long to get ready for a party they do not wish to attend, that the party is nearly over by the time they arrive.
