Assuming that the participants are all of age (which is a necessary predicate of consent), I think that incest should not be illegal. However, incest which leads to a pregnancy and birth of a child should allow for the child (or a guardian on the child's behalf) to sue the incestuous parents for damages for genetic disorders, or for the state to imprison the parents if they were unable to pay.


I think it should be legal. Inanimate objects such as corpses are simply property, and human corpses are property that does not belong to anyone and must be disposed of by law. Sex with an animal corpse might lead to valid claims for damage to property (for example, a cow that was to be sold to a rendering facility but was damaged during the sexual act), however. Necrophilia with human corpses could in certain circumstances give rise to civil lawsuits for intentional infliction of emotional distress (for example, having sex with a corpse and sending photos of the act to the grieving relatives).

While I personally find both sexual acts to be repellent, I cannot find any legitimate reason to make either illegal.
