In the test session of a class, the child sitting in the middle did not study, so he turned to the two children next to him to copy. As a result, he himself received higher scores than the two friends sitting next to him with distorted faces because he felt life was too unfair.
Or a professor conducts experiments through tests when students think that the ideal society is that no one is rich, no one is poor. He adds the total scores of the tests and divides them equally. The result is that the average score gradually goes from B, down to C, D, and then F. The diligent students are increasingly bored, the lazy group is initially very happy but then also not happy, leading to arguments, doubts...
The two stories are just assumptions illustrating the feeling of injustice that one, or many people, feel when something happens to them. For example, in sports, in elections, the football world once felt injustice for Wesley Sneijder, Andres Iniesta, Franck Ribery, Robert Lewandowski, Erling Haaland because they did not receive the Golden Ball despite having an excellent year. The 2025 Vietnam Golden Ball election also left a similar aftertaste, in both men's and women's categories.
Why is it unfair even though there are specific criteria for the votes? Because in the end, the perspective of the voter is the decisive factor. Some people rank the titles in the priority position, others consider their form, role or influence important. Not to mention that their votes can also be affected by other factors, such as coaches voting for their team's players, compatriots even though they are not in the Top candidates...
So of course, when you are on the opposing side, the feeling is injustice. And when you express and share that feeling, some sympathize, some oppose, put back pressure - which is also a kind of injustice to other people's emotions!? Clearly, in games where you have no control, like you can't always ask the referee to raise the flag and blow the whistle accurately at 100%, then injustice is just a component in the flow of life.
So, what is injustice and how dangerous is it? People say, there is still controversy, there is still frustration, there is still noise about injustice, there is still hope. But it would be worrying if it were true as Bertolt Brecht said: "The greatest injustice is to consider injustice as normal".
