So would you prefer these parents abort their children? No one is perfect and many parents try to instill values in their children but they grow up and go their own way. I'm sure it is heartbreaking for a parent but your description was just disgusting.
Yes, blame the kids because their parents are failures. This generation of youth will fail spectacularly because their parents failed where parents in previous generations succeeded. They have not passed on values, in most cases they pass on parasitism. And your abortion shoutout is pure straw man
