One of the things that is fairly common in many religions is some sort of erotic relationship between gods and mortals. Especially in various pagan pantheons, gods frequently have sex with mortals, often resulting in the creation of some sort of superhuman child. This is where we usually get the heroes of many of these myths. These heroes are able to stand up to gods and monsters of all kinds, but not all of the children created from these unions are good. In fact, some end up being vicious monsters or even just powerful humans using their godly abilities for evil. Either way, the union between gods and mortals ends up creating a powerful elite class of beings. With that being said, is it ethical for gods to ever have an erotic relationship with a human if the union can create such powerful and dangerous beings? Furthermore, when there are powerful and immortal people sleeping with changeable mortals, this creates a whole other set of issues involving the large power imbalance between the two people involved.
