Were you 'wrong'?
You did violate the law, which had no ill or injurious effect on anyone (irrelevant, by the way); so you were 'illegal', a 'scofflaw'.
You were not dangerous to yourself or anyone else, the common standard in society today for 'right' and 'wrong'. (The whole "no blood, no foul" rule)
I would likely have done the same thing, and not A.) asked anyone if I was wrong, 'cause I knew I WAS; and B.)not thought about any justification for it. It happened, all survived, and only one person (whose opinions you would not have changed one iota) saw it.
There. You were wrong; acknowledge it and move on, as I have.
