So we do not come to right or wrong through our pleasures or pains or through the process of education.

With regard to your dismissal of education as a source of morality,

It is too challenging to give a general definition of right such that a person would be able to consistently apply the concept in a wide variety of circumstances or that the overarching majority of people would assent to.

Why do we need a general definition that applies consistently? Morality is a complex topic as it goes, and that's why children and occasionally adults have trouble identifying right from wrong.

I have some questions about your analogy of showing a video of stealing to a child.

But this is inadequate. (1) would not teach the child the resources for determining which other actions are wrong. He only learns that stealing constitutes some sort of violation, but not the reason why. (2) is problematic because the “causes harm” becomes the criterion that the child will use to evaluate the rightness or wrongness of an action.

Why not then, explain to the child that stealing is wrong because the stealer did not earn a right to the taken object instead of saying "someone was harmed/this is wrong"? We can say that the stealer did not work for it, had no approval from the original owner, and work on from that? It doesn't have to be a simple answer.

A problem with causal perception as a source of perception of right and wrong is how the concept of right from wrong differs heavily from culture to culture, with some things being revulsive in one culture, while completely acceptable in another. Take the V-victory sign, for example. While perfectly acceptable as a photo pose in some cultures (America, England, etc), it is taken to be a "up yours!" gesture in other countries and invites hostility.

Does the unknowing innocent tourist feel revulsion upon seeing the V-sign in a photo prior to learning of its meaning in another culture? Probably not.

We can explain deviations in moral judgment through our notion of moral sense.

Wine analogy about perfect and imperfect noses

That implies moral imperfection in those who have a different judgement of right from wrong simply because the individual is imperfect. While this can be taken to be true in the case of sociopaths and such, this cannot apply to people who derive their values from different cultures (unless one takes their sense of morality to be imperfect). Thus, this analogy isn't really applicable for your argument.
