Well, I absolutely agree with all that you just said. But still, knowing what sentences the judge can dole out is important. The problem with mob-rousing stuff such as apostasy... or Frankenstein-monster raising, or being Black, or a Hugonot, or an adulterer, depending on context... is that you could easily be subjected to "mob justice", and there would be impunity for your murderers: Pontius Piwatus keeps his hands cwean, and evewyone is happy (the dead can't compwain).
