One could easily just as argue that the USSR is what caused the war to be so brutal. They raped, they murdered, they pillaged just as much as the "Nazis" supposedly did. They did so many ghastly things that it's no longer denied but a basic fact. War crimes were undoubtedly committed on both sides, but the Soviets were far worse.

The Germans were fighting not just for their Fuhrer, just for their own country, not just for their family or themselves. But all of Western Christian Civilization. The Soviets were going to attack first; that was without question. Thus, it only made sense to attack them first; it was a smart move and would have worked had it not been for the harsh winters and illegal Land Lease deal by the United States and their Jewish-controlled government by FDR.
Could you elaborate on what you mean? This is literally what the National Socialists, such as Goebbels, stated. That propaganda isn't effective because it is composed of lies but because it is made of truth! (Paraphrasing, of course)
I've discussed this above.
Had the city surrendered, people wouldn't have suffered as much. It's a war, so naturally, people are going to suffer on both sides. I'm not saying this to wash away or ignore the people's suffering but to recognize the reality that war isn't pretty. And despite the fact that this war was completely justified on the German's part, it didn't mean it was going to be any easier. The Soviets weren't going to just surrender, so naturally, people suffered as Germans destroyed their supplies, which would have undoubtedly reached the hands of the enemy soldiers. Not to forget that civilians took up arms against the Germans, on their own accord sometimes, and others due to the force of the Stalin government enforcers.
In war, you can't save or protect everyone. It's simply not a possibility, especially not with their technology. Hell, even with our modern technology, people are killed from indirect missile or artillery strikes, both civilian and military allies from friendly fire. Perhaps some Germans didn't care, but that doesn't mean the invasion force as a whole or Hitler didn't want to avoid unnecessary civilian casualties.
The war was awful. Obviously yes. Everyone wished it could have been avoided, and if it hadn't been for the Jews, then it truly could have been. But they didn't want that. They wanted the total destruction of National Socialist Germany before it could become either too powerful to be stopped or for the world to realize that their way of life was far superior to any other and want to become National Socialists themselves. They got what they wanted at the cost of dozens of millions of innocent lives on all sides. Hitler didn't want it; he truly didn't. But if he didn't fight, he would have been destroyed via Poland as they had been building up their military to strike Germany first. And with the violence of Danzig, Hitler had enough. It was time to strike back and hard at the evil Jews who had gone one step too far.
