You must show no pity for the guilty! Your rule should be life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
The God of justice: firm, strict, unmoving, unbending. If you break the law you must be punished to the fullest extent of the law. There is no wiggle room there is no escape. Justice is an iron unforgiving fist and so must it be. Justice and fairness for all means people cannot and should not get away from the consequences of evil. But yet somehow this is not a cause for celebration. All humans deep down know they are guilty. Is there a way to escape justice and still be "right"? Only if somebody takes justices punishment for you. God himself steps forward in the person of Jesus Christ and says I'll take their guilt have no pity on me! Justice is served, the guilty are free, and a life-changing relationship between the human and the Divine is born.
