It just reeks to me of him being jealous of people who don’t have kids and/or him regretting being a parent?
Perhaps. I don’t think there’s much here to substantiate that reading though, even with the context. I’d want a bit more evidence if I were to incorporate that into my appraisal of him.
You can judge someone to be morally repugnant without interpreting everything they say/do as an extension of the things that make them repugnant. It doesn’t lessen the repugnance.
Again, if we read it as he literally said that, then sure I’d agree the behaviour is not okay. Given the context of the quote, I’d want more evidence to take that quote literally.
