Cheating a friend is not considered ethical or appropriate behavior. Integrity and trust are the cornerstones of building and maintaining friendships. Cheating can lead to a breakdown in trust, damage to relationships, and long-term negative consequences. From an ethical perspective, cheating a friend is not only unfair to the deceived person, it can also put the deceiver in a moral dilemma. If personal interests conflict with the interests of a friend, honest communication and finding mutually beneficial solutions are usually a more sustainable and healthy approach. In addition, once trust in a relationship is broken, it is often difficult to repair. Therefore, it is worth pondering whether it is worth sacrificing long-term friendships in exchange for short-term personal gains.
