Frustration and anger as a result of denied justice CANNOT be a justifiable cause for a premeditated heinous crime. If anyone is denied justice, then he/she should put up his/her case to God and patiently wait for His intervention.
True justice would involve Anmon making reparation for the evil that he did to his sister. When Amnon was killed, his sister wasn’t unraped, and nothing was truly repaired. Therefore the killing of Amnon did not truly get justice for Absalom’s sister.
When there are permanent damages, perfect restoration can be impossible for humans to make. The only kind of authentic reparation that can be made is through prayer and perhaps some concrete way of Amnon doing something for his sister that honors her dignity. He could be required to offer sacrifices for her or make a daily prayer devotion for her healing, for example.
Let’s imagine for an instant that, instead of doing nothing, David ordered Anmon be put to death. How would that be any different than what Absalom did?
Deuteronomy 22:25-27 clearly states that Anmon should have been stoned to death. People saying “just let God deal with it” seem to be forgetting that God already put down how this should have been dealt with (the laws in Deuteronomy were put into place long before the time of David).
Exactly. The death penalty in the Torah was not something that people could just take into their own hands. It had to be imposed by the local authorities, and the witnesses were the ones who had to cast the first stones.
