He'd be the least evil one. He still had evil ideas, but everyone else was way worse. In fact, they considered him chump change and constantly attacked each other. That's how he won, they destroyed each other until he was in charge. Then all the wackjobs still alive joined behind him, and had a power struggle to take over. Hitler didn't seem to care so long as he had power.

Most Germans wanted a united German people, a thing promoted since the 1860's. They created camps for people they intended to send away those people somewhere else. Several countries have stories of being asked how long it would take to move people out of the country. The military would wait and then invade.

So many people refused and ended up in camps that it became a real problem. They had no where else to be placed and winter was killing them.

The rest you probably know.
