So there’s a chance that he would rather remain an Eved than become a full-fledged Yisroel, yet I’m misrepresenting the Gemara when I say that “The Gemara says that not necessarily would a slave desire to be freed”?
I am also referring to the many anecdotes that include slaves. Shmuel compensated his maid, Rebbe’s maid was highly esteemed, Rebbe Shimon ben Gamliel’s would ask him intricate Shaalos worthy of a Yarea Shamayim. There are others that don’t come to mind right now.
I don’t know the desires of an Eved Kenaani of a Goy, nor does it make a difference. The Torah was not given to them.
