No for the cultural reasons for the taboo.

Incest has the capacity to more than anything else known to humankind destroy the basic family unit. Husbands having an affair. Wives having an affair. These to pale compared to the damage that is done to the basic family unit when one of the parents has sex with one of the children that these two adults have brought into this world. Whether you base this on religious beliefs or just basic knowledge of people and how the react and relate toward each other, I dont' know of any recognized authority that doesn't not agree with the above statement.

Mom and Dad have a son. The son is now sexually mature. So son seduces the mother and succeeds. Make no mistake about it, in the very vast majority of family units, this family is now screwed once dad finds out. This is why in the wild, the male head of the pack kills the younger males that also are his own sons.

Children having sex with either parent is going to not only destroy the family but most likely result in some sort of warfare if all things are allowed to take their course.

It doesn't get much better when the son takes on the sister in terms of damage to the family, though it does cause major problems as well.

There was a time when first cousins were allowed to marry. Even half brothers and half sisters. We now know that this causes major genetic problems down the road.

These my mother walked on me while I was shaving and I dropped my towel and she saw everything are not incest unless they lead to something that is incestuous in nature as in a sexual act of some kind.

I know that there is much more that can be written by people on why incest is a taboo act in a family. I'll not steal the next poster's thunder by listing all the reasons here. I'm sure there are others who can list many.
