He was a genius, yes. He fought hard for what he believed in, yes. And a lot of on-going contributions came from people under his rule. But he's still evil.

He WAS evil. What he did cannot in any way be justified or seen differently upon.

Killing everyone who was jewish, anything but blonde and blue eyes you were gased, twins you would have been experimented on. Ugh it disgusts me.
Good politician? maybe. Good person? is a different story.

I found this an interesting read on Nazi medical experimentation (bear in mind it's Wiki so might not be 100%). Of course the experiments are horrific but they have been said to have been the most beneficial set of procedures to modern medicine than any other this century.

Wow, that is pretty interesting. Too bad you had to actually kill people to perform those experiments, lol.
