What is the difference between constructive criticisms and name sake criticism ? What pleasure a critic derive from their criticism?

Constructive criticism is the one which gives scope for betterment or improvement by applying correction measures to criticized facts. Its basically a opportunity for growth/ development of the person, whose work got criticized and accepting the truth as it is.

In name sake criticism, it is basically deceiving personally by having a name sake criticism as you think that everything is fine and no need for any betterment or improvement. stops knowledge development.

Pleasure development of the critic is based on the real criticism and the intentions of the criticism. If it is true and real sincere criticism means pleasure is responsibility, honest, duty and making others to develop based on their true criticism.

If wrong intentional and malafide criticism is sadism.

My2 cents.

A constructive is the art of giving critical feedback which encourages a person to grow and to not feel bad. Constructive criticism improves a person's behavior and avoids blaming and personal attacks.Constructive criticism has a positive tone and focuses on clear, achievable objectives.

The difference between constructive criticism and name sake criticism. Constructive criticism improves a person's behavior, encouraging positive changes. Whereas name sake criticism condemns and discourages the person.

They feel happy about what they are doing hence unknowingly they keep criticizing others.
