I am sorry to be the one to have to tell you this but life is not fair. Justice does not always prevail and the good guy doesn't always win. Every action, every decision that we make has a equal reaction or consequence. There is no fairy tale or happily ever after. Happiness is a state of mind. Sometimes we have to just hunker down and wait for the storm to end before we can be happy again. My advice to you since you are search for "Justice in life or over all" would be to work hard and become the best you can be in what ever field you wish to study. With wisdom and confidence you can over come most obstacles.
