The thing is that what the Emperor considered the gravest sin to be was disobedience to his will not insanity, murderous rages or any of the other faults his sons had. It was that ego driven vision of his sons as game pieces to moved at his will rather than individuals with wills of their own along with his inability to empathise with them that led to the Emperor's many mistakes & enabled the Horus Heresy to occur.
