He doesn't want to be helpless because he is weak. He doesn't want his fate to be in someone else's hands. So he can only strive to grow stronger.
The opposite can happen too. He might be the one who is cheated at a business establishment. Whether he can swallow the offense or fight for his right and interest will depend on how strong he is.
Helplessness and disrespect because of weakness is something he has already experienced recently.
His mother and some people used his precious students, who he needs to earn Karma, as baits to attract the beasts that they want to fight.
They did so without asking for his opinion or his permission. They also didn't give him anything from what they gained.
That is worse than being cheated. Yet, he couldn't do anything about it.
His mother had told him that they informed him of their actions because they respected him. But he found that respect lacking.
