It's challenging for sure, but one I knowingly signed up for. Ethics has always been an area of interest for me but this is definitely applied ethics; there is no vacuum in which to ponder, these are my kids! I want them to have the inclination and ability to determine an objective right from a wrong, although as @thedamus noted above, mistakes need to be made along the way. I want to equip them with the perfect toolkit but not only is that impossible but it would also hinder their ability to come to their own, independent conclusions.
