I would have thought that the difference can be attributed for the most part to the difference between Jesus and Paul as teachers and to the different conditions of a renewal movement in Palestine and emerging churches in the Gentile world. One thing I would stress is the importance of the eschatological narrative: Israel’s sin is fundamentally rebellion against the covenant God; Gentile sin, for Paul, is fundamentally idolatry and the rampant sexual immorality that he believed characterized Graeco-Roman society.

But the formal differences can also be exaggerated. Jesus mentions specific sins (lust, false witness, hypocrisy, anger), and Paul, as you say, has his principles.
