You make sweeping statements about Pope Francis's predecessors deviating from Vatican II yet offer no specific examples. Yes, you accuse Pope Benedict of pursuing the narrowest and most negative positions on primacy of conscience. Both he and Vatican II, however, never deviated from the age-old teaching of the Church. 
Conscience can never be the final arbiter of what is good and evil. God is the final arbiter and to claim that conscience is absolute is to put one's conscience above God Himself.
