It's the parent's job to teach the child from right and wrong. This mother taught their child the wrong thing and now these kids are going to teach their siblings to have love with each other.
No, the mother taught the children what SHE thought was right.
Get this through your five foot thick titanium skull. THE DIFFERENCE BETWEEN RIGHT AND WRONG DEPENDS ON AN INDIVIDUALS PREFERENCE. NOT FACTUAL EVIDENCE. Also, Kingdaro never said he supported incest you dumbass. He just doesn't care either way.
