According to the Oxford languages site (the one Google search uses for definitions), hypocrisy comes from the greek hupokrinesthai meaning to play a part or pretend. It is defined as ‘the practice of claiming to have higher standards or more noble beliefs than is the case.’
Hypocrisy is the practice of engaging in the same behaviour or activity for which one criticizes another or the practice of claiming to have moral standards or beliefs to which one’s own behaviour does not conform. In moral psychology, it is the failure to follow one’s own expressed moral rules and principles.Wikipedia
Oxford languages define integrity as ‘the quality of being honest and having strong moral principles.’ It comes from the Latin integer meaning ‘intact’.
Integrity is the practice of being honest and showing a consistent and uncompromising adherence to strong moral and ethical principles and values. In ethics, integrity is regarded as the honesty and truthfulness or accuracy of one’s actions.Wikipedia
In a world full of hypocrites, be a person of integrity.
