Man is a vindictive creature, in many ways. The Word of God says "vengeance is mine, says the Lord." Man is not supposed to take revenge on anyone, regardless of how reasonable the reasons may seem. And in this instance, it such a flagrant waste of money that nobody can be justified. That money could have been spent on starving children anywhere around the world.
Yes, people tend to be too focused on revenge. Revenge is never good. It leads people to harbor negative feelings for long periods of time. However, stories like this may be less about revenge and more about challenging oneself to be different and then to show your accomplishment later. This particular story is funny.
I don't believe that this man was focused on revenge. I believe this gesture was more for himself than anyone else. It must have been humiliating for him to be dumped by a girl for being too poor. Years later, I believe that he wanted to prove to himself that he was worth something and that he had become successful.
Many people experience adversity in life. The man that was dumped by a woman for being too poor to take her to the movies was definitely motivated by that event. Years later, to prove his success, he booked several IMAX theaters in Beijing to show off his wealth. Therefore, it can be said that those like this man enjoy getting revenge for past slights in life. However, there is nothing wrong with being motivated by revenge as long as it will create a good outcome one day.
