Well, perhaps for the sake of clarity you would be willing to list some beliefs you deem to be heresy. We can have a much more intelligent conversation if we have some concrete points to discuss. Right now, this thread is far too conceptual. We all agree in theory that heresy and apostasy will not be good on our " resume"...
Some on this thread are not ready to agree with your OP because we have no idea what beliefs are being deemed heresy. Churches split over all kinds of minor doctrines. Some Christians can be downright petty and obnoxious and label anyone with a different view a heretic. Obviously, God isn't going to second their petty pronouncements of judgement on others
