Tehillim. Psalm 38 - The Calculus of Guilt

This chapter presents a sense of guilt and remorse for (an unidentified) sin. And yet, the sinner is suffering at the hands of violent enemies. Should past mistakes justify the violence perpetrated against him?? Should one perennially be a victim because one has erred? Or might one appeal to God to appreciate ultimately who is on teh side of good, and who on the side of harm and evil?
