Godcucks believe that god literally dictated certain laws to humanity, like the ten commandments.
Can you imagine how good and complete and profound and perfect ten universal moral laws written by god himself would be? So why is it that a literal child could improve on the ten commandments without effort?
Let's take one of the commandments: "thou shalt not take the name of the lord thy god in vain." Imagine if we got rid of that commandment and replaced it with "thou shalt not rape" or "thou shalt not keep slaves" or "thou shalt give his or her children the finest education possible." Is that an improvement?
The answer to any sane human being is 'yes'.
Let's take another commandment: "thou shalt not steal." Couldn't we improve this by changing it to "thou shalt not steal unless your child is about to starve to death or something and there is a loaf of bread you could take that would keep them alive".
Godcucks will literally argue that these changes make the commandments worse.
