"Resentment seems to have been given us by nature for a defense, and for a defense only! It is the safeguard of justice and the security of innocence"

Adam Smith's quote recommends that bitterness is a natural feeling that serves a purpose. It is a defense mechanism that helps protect us from injustice and damage. It is a way of making sure that our rights and boundaries are appreciated and that we are not made the most of. Resentment can be an effective emotion that can help us stand up for ourselves and defend what is right. It can also be a warning sign that something is wrong which we require to do something about it. Ultimately, animosity is a tool that can assist us protect ourselves and our innocence.
