What is the consequence of not doing for your sake?
1.
Malbim: If I would do for your sake, it would depend on merit and liability. When they will sin again, He would exile them again. However, since I do not do for your sake, rather, for the honor of My profaned name, perforce it will be in a way that they will not sin again, and He will not need to exile them again and there will not be more Chilul of His name.
