Were the allies right to divide Germany for the restoration of Europe?

It's a trick question because Germany was not divided for the purpose of restoration, it was divided because Stalin's army had occupied those areas of Europe by the end of WWII, and Stalin wanting to invade Europe anyway took it as a moment of opportunity to simply keep his newly occupied territory.

However, in regard to was it good or bad - well, from my understanding the allies took good care of Western Germany and West Berlin, and after the Berlin Wall fell many were surprised to see bullet holes still in some of the buildings from the Battle of Berlin. The Eastern part was not as well off.
