Yes, but mostly after I had kids (and especially teenagers) and realized for myself that, yes, I was the asshole. The fact that humans let most teenagers live to adulthood says a lot of good things about the human race.
Edit: To expand I have more sympathy with my mother because I know of some of her traumas growing up. But I have a harder time to excuse my father.
After having one (1), I realized that my “shitty parents” were actually amazing superhumans, despite all their very human flaws.
Luckily I love my parents but otherwise I'd be soo mad.
