I think Lennon was more of a nihilist than anything.
But even more than that, he was just loony-tunes, a curse carried by many talented people.
He MOSTLY raised himself from the age of 10 onward and never had a strong male influence in his life...well, except for those fellas singing on the radio, something he very early on learned he could do as well, if not better than them.
By the time he was 19 he was "nearly famous" and by the time he was 25 he was the most recognized man in the world.
Nobody ever told him "no".
How could he not be totally screwed up in the head?
But, dam he could sing. A melodic genius.
