emotions are intended to be guides for behaviour but as they are so widely misunderstood they are able to be misused so they are widely misused most people regularly misuse emotions and some habitually misuse them
a common form of this happens when negative emotions " possess" a person which is almost a routine function of emotions then the harm done to others leaves a wake of destruction others are affected, hurt, offended, aggrieved when this behavior causes an almost inevitable reaction from its victim more emotion, eg anger, shouting, indignation etc are used by the perpetrator this is used to silence the victim and close the argument most people are aware of their ability to do this those who use this method frequently are basically sociopaths it is well known that many sociopaths rise to stardom in their field of endeavour by this method of intimidation which generates tacit support by dint of the victims fear of emotional reprisal the same applies in families, marriages and all partnerships / relationships.
those who are unaware of what they are doing with their emotions or of what their emotions are doing with them are always prey to this behaviour
since one of our goals, rewarded by happiness is being successful, dominant, excelling, etc it is no surprise that many take this happiness thinking this is a good deal and they are able to be unempathic enough to leave their victims unhappy
this is an example of how the different goals rewarded by happiness can be in conflict the outcome of reasonably shared happiness is not necessarily supported
