By the way what chein has said posted is easy to understand for those who have real emunah.
We ultimatley are not G-d and therefore cannot really punish appropriatley, rather we must follow the Torah’s guidance.]
If we cause harm to an innocent individual no matter how worthy our intentions, we will have to pay for the damage inflicted.
On the other hand if a guilty person walks free because we are following Hashems rules then ultimatley it is Hashem the Father of all of us who is responsible and will ensure that the proper things take place.
See Meseches Makkos about one who kills B’shogeig for further elaboration
