I believe the very first brushing I had with serious cognitive dissonance, (at 8 years old), was over this very topic.
My mother and my aunt were in conversation concerning the then recent murder of John Lennon, and said something to the effect of, "well at least we know he will be the one Beatle who will be in the new system". Knowing my father was an unbeliever, I asked in turn, "so it would be better if Dad died now?".
Dead silence.
Stupid me for wasting the next 24 years of my life.
