The person I studied with was an elder and as soon as he saw that he wasn't going to get me to drop my worldly friends he became a real jerk. I told him that I knew many JW's in So CAL where I grew up and that my worldy friends were saints compared to them. He basically called me a liar. (I was not lying, the JW's I knew in CA should be DF'd for loose conduct of all kinds but I didn't know anything about the religion when I was partying with them and so I had no way of knowing that they were hypocrites, living a double life.) After that even though I was still studying, he would put me down in front of the other JW's that had befriended me and say stuff like "oh watch what you do around Drew he thinks we're all hypocrites"so I just finally decided that this religion with all it's fake love they neighbor was BS and quit stydying. He never called me again---so my answer would be no, they don't really care, at least this jerk doesn't
Just to clarify, I do not think all JW's are hypocrites, I'm sure there are many who stay faithful
