The 10 commandments were written in 150-100 BCE (fragments containing parts of the commandments from around this time were found in Egypt).
The 11 Satanic Rules of The Earth were in 1967, according to the Church of Satan’s website.
These are COMPLETELY different time periods. You cannot compare rules made 2117 years apart. The society and culture they were made with knowledge of cannot even be compared.
You can not posit our modern views of the word on rules made in a world where that was not what it mean.
Rape as we know it did not exist then. The idea of rape when the commandments were written was abducting women and sex was not a component.
Rape did not come to mean what it means today until (at the earliest) the 6th century.
So it was not necessary to add “thou shall not rape” as a commandment in BCE when “thou shall not steal” and “thou shall not covet your neighbor’s wife or anything that belongs to your neighbor” were already included. Women were property, abducting them would have been stealing from your neighbor (and that is what rape meant).
