Shame is a failure to be good, guilt is a choice to be bad. Inexplicable, ie evil. Milton makes it explicable as satans pride,he was himself anti monarchist (NB original design to write satan as tragedy,Shakespearean hubris?).Locke writing against rule &religion (did castellio think Protestants (Calvin) shld be better than Catholics &not use state; Luther certainly didnt).For Milton Adam’s disobedience follows satans. That knowledge withheld isn’t authority, but knowledge isnt guarantee of good.
