Discussion
Crimes of love are amongst the most socially shocking in the way they break very strong rules against incestuous relationships. The children of incest, of course, can easily be genetically damaged, and hence such relationships are strongly banned in all cultures.
However, when this act is accidental, then a confusing conflict is set up in the viewer, who is both disgusted by the crime and sympathetic to the lover who themselves will be feeling even more internal conflict. The result is a powerful emotional dilemma which pulls on the heart strings and provides a strong story element.
