My question is why is it okay that two different regularizations of a one loop contribution to the full propagator give two different answers? Are the finite parts for all regularization schemes the same? If that's the case, do the divergent parts only contain information about high energy momenta so the fact that the divergent parts are different just represents the fact that our theory isn't well defined for the high energy modes.
