Creating resentment is a process of causing someone to feel bitter or hostile towards another person or group. It can be done through words, actions, or even by withholding something from someone. Embittering someone is one way to create resentment, as it can lead to feelings of anger and frustration. This can be done by making someone feel excluded, belittled, or ignored. It can also be done by making someone feel like they are not valued or appreciated. Ultimately, creating resentment is a form of manipulation that can have serious consequences.
