Can Justice and mercy co-exist?

I think that mercy and justice can co-exist.
Punishment within the justice system can be merciful. But there are still cases of justice without mercy but they can be mutually exclusive. On the other hand, mercy is also considered to be a part of justice. It is important that an eye for an eye is not justice but considered as revenge and should not be misunderstood as justice. The purpose of justice is not revenge, but to ensure nobody is at the losing end. Although in some cases, punishent can be given out but more often, mercy and the act of forgiving are more effective ways of securing well being for all. Mercy gives the offender an opportunity to turn over a new leaf and at the same time it also gives happiness to the person showing mercy. Nobody is at the losing end. An example of this is the Iranian example. An Iranian women was disfugured by acid by another man and in the process, lost an eye. The Iranian law allows her to make the man lose an eye to but she chose to forgive. This is a good example of justice and mercy co-existing. The law sentenced the man which is justice, and the forgiveness of the women as mercy. Thus, I believe that mercy and justice can co-exist, but there is always an exception to everything.
