"Ill Will" is a psychological term that refers to a feeling of hostility or resentment towards someone or something. It often arises from perceived wrongs or injustices, leading to negative emotions and actions. This concept can manifest in personal relationships, workplace dynamics, or broader social interactions. In literature, "Ill Will" can also refer to themes of revenge and betrayal, often explored in novels and films. For example, the concept is prevalent in works by authors like William Shakespeare and Edgar Allan Poe, where characters may harbor deep-seated grudges that drive the plot and character development.
