From a moral and ethical point of view, it is inappropriate to deceive friends for personal gain. Friendship is based on trust, respect and sincerity. Deception will not only destroy this trust, but may also cause emotional harm to friends. In the long run, this behavior may damage your interpersonal relationships and even make you lose friends. In addition, deception may bring short-term benefits, but in the long run, it tends to bring more negative effects. Honesty and integrity are the key to building healthy and lasting relationships, and they can also help you gain more respect and trust in life. If you are facing a certain predicament and feel that you have to obtain benefits through deception, it is recommended that you consider other more honest and transparent ways to solve the problem. Honest communication with friends and seeking their understanding and support often bring more positive results than deception. In short, deceiving friends for personal gain is not only unethical, but may also have a profound negative impact on your interpersonal relationships and quality of life. Choosing honesty and integrity can not only maintain friendship, but also make you feel more peaceful and confident in your heart.
