People write for fun but few write to curse and few write to dictate ..

People express their emotions might be sad or joy what they face.
Few people write to hurt others
Few people nowadays write to reply back their decisions but they keep the face to face conversations so nicer to be.
Few people vent out their whatever they think with imbalanced emotions that they lose what they are thinking what .

So writing is good or bad, i would say freedom of speech or write is not bad until the person loses ethical balance of sukshma, the budhi, and unethical thoughts of brain with heartfelt emotions of righteousness.
Hence dont write what you feel it shows your actions which becomes your basis.
