revenge vs justice(Macbath)

…

…injustice of revenge. Punishment is a must for a better society, but revenge is not a suitable form of punishing. But people still insist on the revenge and create more problems. The only logic solution to these problems is to put them on trail, and hope for justice. Instead of taking revenge or killing each other, people should seek justice, go to the courts, do not use power, more better is to forgive and forget.
