Psychological analysis 2

I like observing people and it gives me enormous courage to judge people, try to get their point of view and their justifications for their own actions.
This is the profile of two guys I have met and a brief analysis of them. As a psychological case. Please tell me your opinions and share if you have met anyone like this
Reynolds is a muscular guy, who loves van diesel movies, and a fitness freak. He likes to drink, work out and watch action movies, Very funny and also overly sensitive. He takes much proud in being from a ‘working class’ background and believes that he can be a self- made man. Though he knows he doesn’t have the intelligence of a Steve Jobs or Bill Gates, he wants to assert to his power, not in a harmful way. Jason, the geek stayed with him during their college. Jason is an introvert, fond of reading great philosophers, Early American novelists and Existentialism. Reynolds couldn't understand all of this and he thinks there is a psycho in his room. His fellow companions in that hostel, guys who all are sort of control freaks gather together and finalize a plan. They think Jason doesn't know basic etiquettes and it is their commitment to civilize him. They start teasing Jason and one day Jason hits Reynolds. Reynolds didn’t say anything believing an uncivilized man must not be punished in a harsh way. Even though it was a mistake from Jason that he didn’t intentionally hit Reynolds. After that Reynolds changes his attitude towards Jason, kind of avoiding him. In a drunken party, Jason goes wild and embarrassed by his own classmates. Then Reynolds, as a ‘tragic hero’ goes to rescue the geek. This enhances his personality in the group as a magnanimous guy and Jason’s value falls drastically. Suddenly he becomes an ‘immature, idiotic’ personality, who needs rebuke by everybody. Reynolds never liked the man, always belittling and abusing him, for even the slightest fault he had made.
I would like to know is there a syndrome related to revenge? I mean any petty-matter related revenge? I have been doing a case study on human interactions so I would like to know more about this thing. Thanks a lot.
