It is said that there was a line like this in the drama "Spirit". "Why do good have to constantly prove itself when evil goes his way so relentlessly?"
.
You're talking about this line, so I'm going to open up the bear... the podium (I don't know if this is something that works within martial arts, but it feels like it's being implemented in reality)
.
1. "Then do it. It's easier to give up." -> Buksan High School director's grandfather version
2. Who led? Who guarantees that he is good.

I don't think there is an absolute good or bad. Sometimes "our side" and "that side" are divided, but depending on the situation, you can bring "the other side" or you can sympathize with "the other side." And crucially, our side is not just right, and the most dangerous thing is the cruelty that comes after I believe that it is "good."  

During the Korean War, Korean right-wingers were greedy and dirty, so they did not participate in the massacre at the Korea Press Federation. They believed that it was good. In their eyes, the 'red world' was hell, and they claimed themselves to be heavenly angels to prevent it. What about the left-wingers? The world of pro-Japanese group, the landowner's reaction, was hell, and they were ready to bleed to destroy it. Even with an all-out war to build resentment over the next 100 years.

It means that when people, left or right, were asked, "Is this okay?" they could shout out loud. "Why do good have to constantly prove themselves when evil is going their way so relentlessly?!" That being said, even a Yoon Suk Yeol rebellion criminal could scream like that while drinking in Yongsan. Everyone believes in what they want to believe, and they want to believe in what they are good.

Good does not need to be proved to others. It is to be seen and seen. Rather, you need to constantly ask yourself, "Am I right? Is this right? Is this the right direction? Will there be no shame in the future? Is there anything wrong with my past? I have to keep asking like that. The darkest scenery is to turn outward without asking, "Why do I have to prove my good?"
