My husband and myself are raising our 4 year old son and since I have had him I have found out that I cannot have other children and we are looking to adopt a brother or sister for him but the waiting lists are so long in canada for a child he will be grow up by then. Does anyone know of an agency or someone willing to do a private adoption?

Basically, nature vs. nurture. Like, do you think a psychopath is born or made? Do you think some of the world’s finest could have turned out to be serial killers if they’d had a different upbringing?
Also, what kind of parenting do you think constitutes “good parenting” or “bad parenting?”
