You actually cannot conceive of how you reasoned as a 13yo. You can remember your emotional memories perhaps, but your ability to cognate something then as compared to now, is precluded by the very way our brians work.
So while at 13 you knew at some level that 'raping a 72 year old woman was wrong' - i'll almost guarantee it was in the context of "I'll get in trouble if I get caught". I remember a fight I got into at age 13. My grandmother had nitted me a ski sweater and hat with a pom pom on top. I wore it to school. One of the "tough guy kids" grabbed it and started playing keep away with it.
So I did what I thought i'd been taught - IE it was something I'd been taught but in a different context, one where I had no authority to turn to - I went to grab the hat of the ringleader. he tried to dodge, slipped and fell in the icy mud and came up swinging.
When the Bus Monitor broke up the fight I was sitting astride the kid pummeling his face and I remember wondering if I was going to get in trouble for the blood coming from his lips and gums. But I had ZERO SENSE that anything that had happened was "wrong".
As an adult I would never have reacted in that manner. I cannot even begin to think the way I did back then because my brain literally works differently now as opposed to then.\
Same is true for you.
