It sure is a good start, but I do not think that it guarantees the outcome you want, by any means.
There are, after all, countless cases of kids who had a good upbringing who then proceeded to inflict great pain on themselves and others.
The reverse must also be true.
Not necessarily Karnal, because there is a lot of hidden abuse and violence in children's upbringing. This, many kids who we might suspect had "good upbringing" actually did not. Check out Alice Miller's book on this topic. It's called For Your Own Good.
Thanks for the discussion!
