To be honest you have to admire how advanced their technology was for their time.
For example
Jet Fighters
The Nazi's were the first to create jet powered aircraft going at quite some speed, and to think how most aircraft the world has created was thanks to the Jet Powered technology that the Nazi's had created. This technology was used by all nations more than likely.
The British had a Jet propulsion program years before Germany, but it failed to draw any significant interest from the government. Germans had significantly more interest and funding because the military advantages to Jet powered aircraft were obvious. Britain shat it's pants come 1941 and started dumping money into the program, but by then the Germans already a working prototype. Had the Germans failed in their attempts to create a working Jet engine, the British would have got there eventually, although that may have significantly changed the balance of power in the subsequent Cold War.
Stealth Fighter
The Nazi's also made the first Stealth Aircraft this Aircraft was but a prototype but actually was the first functioning stealth aircraft, they were also creating a bigger version of this aircraft as a bomber, An if this Aircraft was used in the Battle of Britain in large number then their's a good chance that we would of lost the air superiority war due to how advanced these aircraft were. The American's copied this design to make their Stealth Bomber.
The design and materials serendipitously gave it some protection against early radar, but all flying wing designs right up until the end of the war were prototypes, nothing like the Ho 229 ever had a chance of being in the Battle of Britain. Also, the Americans already had companies working on flying wing designs well before the the war even started, they even created several flying wing prototypes just like the Germans did, but these were prop powered as opposed to Jet powered.
STG 44
The Sturmgewehr 44 the first assault rifle in history was created by the Nazi's
StG44 was the first
mass produced Assault Rifle... the Russian 'Fedorov Avtomat' can claim to be the first true assault rifle.
Soviets were even worse war criminals 
i think i have to actually agree with Killar on this one, unless you can provide alternative evidence.
Burden of proof is on you i'm afraid.
edit
Actually, I'll take this one as I'd rather it didn't turn into a massive debate about who was the bigger asshole.
It's well established that the German annexation of neighboring countries started WW2, regardless of Versailles or appeasement, arguably this alone lets us attribute the deaths of all combatants in WW2 to the direct expansionist policies of the Nazi Party, this includes German dead. Coupled with the killing of Jews, political prisoners, homosexuals etc gives us a number well in excess of the numbers killed under the Stalins reign in the Soviet Union (even an inflated figure). Stalin was a massive prick, yes, his policies left a lot of people dead, yes, but worse than the Nazi's? Not even fucking close.
This said, vast majority of countries involved in WWII have blood on their hands.
