The victim would eventually become a perpetrator. In Psychology, this was known as the "Kick The Cat Effect", a chain reaction. When a person was bullied by someone stronger, he would seek out someone weaker to bully, so he could achieve psychological balance.
It had a similar rationale to "those who suffer will one day get their chance".
The cousin's experience had interpreted this point perfectly. Someone had a handle on him, and he had no way to retaliate at all.
After the first "coercion", there were a few more similar incidents. He was subjected to an immense psychological torture every time he did it. He very much wanted to escape from all this horrible stuff, but the other party simply wouldn't let him off. They began to have more and more holds on him, and he drifted further and further away from his initial dream.
The cousin would repent when he was alone. How did he slowly get himself into this irreversible state?
