Interestingly, in Jewish literature (Talmud and further refined by Maimonedes) Epicurus refers to a certain kind of non-believer, not to a sinner for pleasure. See here for example https://www.sefaria.org/Mishneh_Torah%2C_Repentance.3.8?lang...
I always wondered about that because I guess I fell for the "Christian propaganda" as you call it.
