From a cultural tradition devoted to deicide: A open lament for modernity
Early 17th century: from ecclesiastical Latin deicida ‘killer of a god’, or directly from Latin deus ‘god’ + -cide

I come from a long, illustrious and distinguished philosophical tree. One embedded with a deep abiding cultural tradition, that has been habitually, and instinctively devoted to deicide for centuries. (people had to do something before video games) Cynics, we intellectually and logically, killed off hundreds of gods, goddess, and various demigods back in the day.(middle third century-bc to the Council of Nicaea in 325 ad)
These acts of deicide, likely lead to the sudden fall of the cultural traditions and religious practices for all the citizens of the Roman empire by 400 ad.
