There have also been some notable examples where a jew actually can overcome his jewish programming and become a true Christian: Johannes Pifferkorn, that one jew who translated the Talmud so he could warn the planet how evil it was and whos name I cant recall, and Bobby Fischer are all pretty good examples of this. Of course, the number of jews who also falsely convert with the intent of subverting is much higher, at least in the past couple centuries. Thats why the method of vetting Catechumens should be much more stringent in my opinion, right now any degenerate can walk of the street, pretend to convert, and then consume the Holy Eucharist in a state of mortal sin.
