A+. Kids come out with their own personalities which will grow and change in response to events. You can provide some of the events but not all. You can't really control how they change in response to those events. The idea that a child is a tabula rasa, fully shaped by the parent, is harmful to parents and children.

I used to think kids behaviour was 80% nurture and 20% personality.

After I had kids, I would guess it's 80% personality.

It literally says in the article that the mother was a promoter of a branch of philosophy which excuses any act, no matter how dastardly, just as long as the end justifies the means. If she lacked a moral compass it's of no surprise her son turned out the same.

> a promoter of consequentialism which excuses any act, no matter how dastardly, so long as you believe the end justifies the means

That is not consequentialism at all. Consequentialism is just the opposite: what matters is the consequences of your actions, not what you believe.
