I consider one of my parents to be an objectively 'terrible' person. I don't think I 'owe' them a god damned thing. However, due to good fortune, I am a person of some means. Its trivial to me to help them out in a mild sense. I do so not out of a sense of parental homage or heritage or any of that garbage. I do so because they are a person in need and its less effort to subsidize some of their costs than it would be for me to feign love or appreciation for the their failures as a parent. However, if it wasn't them, I'd be helping someone else in a similar position. Why? Because the fact is you do owe the rest of society. The non-sense idea that has never been the case is that we are islands unto ourselves. Only pissbabies who never aged mentally past the maturity of a adolescent believe they are their own making.
