I don't think you guys who are defending this writing get that while it makes sense for him to act that way externally (he would be killed otherwise), it makes no sense for him internally to be ok with this and/or have no reaction. He would likely die if he acted out sure, but the fact that he is not having any sort of internal monologue to showcase that character does want to be able to do something about how he is treated, yet knows he can not due to the situation, is pretty weird.
