They shouldnt be unfair to othersjust cuz ppl were unfair to them nor should they try and take revenge, instead they should be fair to others so that way others dont feel the unfairness they did. they should also be kind and not be cruel just cuz of wut someone did to them
Well, they should obviously tell the person that is being unfair that they are wrong and should stop behaving as they are. Also, try and comfort the person receiving the unfairness as they may be upset.
