Why do people spit out spiteful tantrums!!!!!!!!!!!

Most of us have the opinion that speaking behind ones back is ridiculous and a very wrongful act.Is it so really???????????Damn it!!!!!!!!!!!I dont think it works that way always.................Sometimes its better if people dont let out their emotions(right or wrong) on the spot.Most of them think,what they do is absolutely right and no one on the face of this plannet can question them.It is their mouth that blabbers such idiotic stuff..........i dont deny the fact that man has the "right of speech",but but butttttttttt it is our ears that hear it,and our hearts that pain(THEIR ENTERTAINMENT FOR 1 MIN vs OUR SHATTERED HEARTS FOR YEARS...).Man has no absolute powers,,,,,mind it!!!!!!!!!!!
Being frank is good to a certain extent,i.e if the criticism works well for the betterment,if something good can be learnt by it,definitely not when it hurts others to God knows what extent.There are few sadistic people who wait for such an occasion,to hurl such bitchy words on others(The others here can also be their own friends).It seems like the pleasure they obtain is equivalent to a heavenly meal.Making fun of a person once or twice is quite okkkkkk,it might even get the targetted victim to laugh(this is the optimal condition)futher criticisms might lead to a negative reaction.Why dont people understand this????????????Neither are the people engaged in such Acts perfect,then why the hell do they do it?????????It seems like there can never be answers to such subjective feelings!!!!!!! :( .It is afterall the human heart that should induce basic manners and civic sense in such people to work for the betterment of the society and not to humiliate and degrade the essence of social living.
I dont understand what fun they derive by bitching around????????????I guess im again down with this same old question..........but i just cannot help asking it.
