Why do people criticizing other people for nothing?

criticism is actually giving judgement to such actions. the results would be affirmative or negative depending on the type of criticism one will make.in our day to day dealings with people, to criticize does not necessarily imply to find fault, but the word is often taken to mean the simple expression of disapproval. others make it as an evaluation to such events, works or any action. in my case, i don't just criticize because it would simply hurt people and i don't like that it would be a cause for any break ups of friendship. if we judge it should have a reasonable ground and be subtle in saying words especially be careful with the choice of words.

maybe because they want to voice out their opinion and belief without thinking for that a certain person or action. some time it's give them a little bit happiness to them and i don't know why. but then when i heard a criticism no matter it's good or bad i give it an attention for what they say because maybe I learn from them and wake up call to myself to be good person.

Sometimes people criticize, as if he's perfect. Criticize without thinking, whether that criticism will get people injured or not. And sometimes people want to criticize, but do not want to be criticized.
