Conviction and a greater conviction

Recently I read a book chakravathi thirumagan (commentaries on Ramayana)written by C.Rajagopalachari . The couple of lines fascinated me. The backdrop of the scene was '' who is weak Is it Lord Ram or Ravan? Rajaji says all wrong doers are chicken-hearted by nature but, they camouflaged their originality by their wealth?? and by their so-called pompous lifestyle. He added two things about wrong doers '' to commit a wrong(delibrately) you need a conviction and to confess it you need a greater conviction'' The latter part was lacked by ravanna.
