Brilliant, as usual, and very affective.
Children simply don't have the same cognitive abilities as adults. There is more development in the mind than in the body between 10 and 32.
The problem is we don't have family photo albums for moral development. We look back at our own pasts through the mind of today and can't imagine ourselves as we really were.
And don't mystify your psyche too much. You are who you are today, which is awesome. You didn't kill a part of yourself. You are yourself. It's the sense that you stand outside that to objectively evaluate that is the illusion.
I continue to be amazed.
