I guess my reaction to your comment was that I have no tolerance for people excusing their behavior because they were fooled or because there was peer pressure or because everybody else was doing it.
I think my parents were a bit extreme in how they raised my sister and I to make our own choices about our lives and to be fully prepared to face the consequences on our own. I ran with a bad crowd and I was usually 100% cool with what we would get up to. When I wasn't I would walk away. I was a seen as being sort of a weird guy from the times I would opt out of what was going on, but it had been drilled into me from a very early age that my life my choice and I was completely responsible for my own actions and would bear the full weight of the consequences. If I wasn't down I was out.
Fool me once, naw, you ain't gonna fool me. I make my own decisions.
