Was Hitler objectively bad?

[Anomalocaris]

This is one of the largest problems with Atheism. Atheists can be 'good' people. But everything is permissible...

I have exactly the opposite opinion. Far from finding everything permissible, we Atheists have basic standards for acceptability that are far more rigorous than any a religionist would think about applying to his belief. For example we do not find it permissible to jettison our intellectual integrity to indulge in the absurd belief in some fantasy deity and promiscuously fool ourselves into hoping that it would reorder the universe for us and coddle the most needy part of our personality.

Given how obviously ridiculous the fundamental basis of religion is when seen in light of the body of knowledge humanity have laboriously gathered and systematized, and how contingent were the circumstances that mutated each religion into it's various present forms, to have chosen to believe in god in the 21st century is exactly the admission that one has been very permissive towards oneself and stands ready to accept anything so long as it seemed to fulfill some right combination inner, discreditable primitive needs.

And yes, Hitler was a calamity for mankind. Improving the welfare of Mankind is most atheists' highest goal, and so Hitler was bad.
