Halakah and Mitzvot do not have intrinsic validity. It is a good thing to care for the widow and the orphan, but it is not a divine imperative.

Judaism is distinctive as a convenential religion. There is a mutuality of commitment between God and the Jewish people. Any individual can reject the idea of a covenant, he can try to rewrite it, ignore it are anything else. The actions of any individual says nothing about the true nature of covenant. We could not resolve that issue, so we left it to be solved later on.
