It's really sad what happened to Barny. But I still think his life could have turned out differently if his environment hadn't taught him that he was defective because he had no dad.
The whole arc upsets me to no end. It's like, a single mother cannot be a good parent and a kid without a dad will always grow up to be some emotionally stunted womanizer.
It's demeaning and unfair to all the kids raised by a single parent. The truth is, Barny is a good guy, even if he's not cut out for marriage this season. Everyone is conditioned to want a suburban home near a volvo dealership but no everyone can be happy inside that picture. No everyone can handle it, doesn't mean they're bad or wrong or broken and need to be fixed.
