Nobody forced Hitler to invade Poland. Nobody forced him to make an agreement with Stalin. He let his PRIDE and EGO win.

As for the people he purged, of course the government always tells you they only kill the bad guys. They do that now. "It was only terrorists we killed, it was only the drug cartel members". BS.

Glad you didn't deny the gulags, because yes they used slave labor. Yes they put those people's lives in danger which led to many deaths, even assuming no mass killings by gas. And I wouldn't rule out their capability for mass killings, not when dealing with a bunch of race worshiping eugenicists, not for a second. It's only a matter of means and opportunity for such prideful men as that.
