Just want to point out that people aren't necessarily taught to do wrong at all. Mostly it's the result of imperfect conditions whether that's parenting or circumstantial.
If something is a learned behaviour, it necessarily requires a teacher, JJ. I appreciate that that teaching may not be conscious or active, but passive teaching is just as bad. For instance, if I as a parent, fail to criticise racist behaviour or cruelty to animals in front of my children, I am - effectively - condoning this kind of action, thus teaching them that its OK.
