Not to mention that Hitler was tragic military leader, very immoral man, silly strategist and basically his empire lasted for few years before leading to total destruction of German nation and whole Europe.
I would like also to remember that in Civ5 there is NO STALIN and NO MAO, so your complaints based on "Hitler also should be here" are ridiculous. No Stalin, no Mao, no Hitler. Each of this men was really bad leader (don't even say me about "Stalin industrialized the country", nor about "Stalin won second world war by starting it and making his country to lose over 20 milion people, because of his own paranoid madness") and extremely immoral man.
Hitler was a very good leader, he really knew how to "seduce'' people so to say. As for Stalin and Mao it is a question to debate. Also let's look at other leaders, all those kings, queens and emperors. While I cannot say they were bad leaders, you really think they were moral?? The likes of Elizabeth I, Henry VIII, Napoleon (an emperor who fought for democracy!!! wtf??), Washington (he was also a bad general by the way), Alexander, Catherine etc.. They also did bad things both to their people and others. What I want to say in the end that if you want to rule you must let morality go (the reason why I would never want to rule over anything, ever!)
Looking at Hitler from some nationalistic side, he always promoted his people, their culture, history, glory and accomplishments. So.. looking at it objectively what is worse? Killing millions of people of other nationalities or killing millions of people of your own? (Don't get me wrong they are both bad, and yeah I am not protecting Hitler, just looking at things from different sides).
And yeah, have to say it. If it weren't for Stalin's madness and especially the great sacrifice the Soviet people gave, I don't think UK and USA would have won the war on their own.
In game his 3rd Reich would equal a warmonger who conquered a few cities only to get denounced by everyone and got wiped by the other civs in 4 turns.
And wiping out both Austrian and French civ. . Just joking.
