Might makes right cannot be true because if one is a vegetarian and eats the meat that is supposedly good for you, the vegetarian will become sick.
That which is loved by the gods is considered to be piety
Some things that are loved by the gods are holy.
The gods love all human action that are just.
Euthyphro and Socrates questioned if something is holy because it is loved by the gods or if the gods loved it because it is holy.
When one prays to the gods, thinking that they are benefitting them and making them happy, one doesn't realize that they are simply asking more of them rather then giving a service to them.
Even when one sacrifices something to the gods, they are only giving back what the gods had in the first place.
