Honor Thy Father and Thy Mother

The fifth of the Ten Commandments addresses the respect God expects children to give to their parents.

Honor thy father and thy mother, that thy days may be long upon the land which the Lord thy God giveth thee.” (Mosiah 13:20 — Compare with Exodus 20:12)


-How does this commandment apply to children who have wicked (or in secular parlance, highly unethical) parents?
