Your question: "Was Hitler a Christian?"
Yes. In particular, Adolph Hitler was a Roman Catholic, the result of his socialization since childhood.
The only qualification for being a Christian is to believe there exists some god, or offspring of a god, by the name of Jesus, that god being based on the stories in the four Gospels of the New Testament of the Bible.
None of his should come as a surprise to students of history. Only con artists and naive believers would attempt to rewrite history on these sort of issues.
Just as some pathological liars say that Muslims who engage in the Islamic war on humanity are not really Muslims, so-called Christian apologists have claimed that Adolph Hitler was not really a Christian.
By their standards, there are very few Christians in the Roman Catholic hierarchy.
But they do not go that far, I presume because their pseudo-explanations are only meant as public relations.
The also tend to overlook this history:

"My feelings as a Christian points me to my Lord and Savior as a fighter. It points me to the man who once in loneliness, surrounded by a few followers, recognized these Jews for what they were and summoned men to fight against them and who, God’s truth! was greatest not as a sufferer but as a fighter. In boundless love as a Christian and as a man I read through the passage which tells us how the Lord at last rose in His might and seized the scourge to drive out of the Temple the brood of vipers and adders. How terrific was His fight for the world against the Jewish poison."
- Adolf Hitler, in a speech on 12 April 1922 (Norman H. Baynes, ed. The Speeches of Adolf Hitler, April 1922-August 1939, Vol. 1 of 2, pp. 19-20, Oxford University Press, 1942)

"No matter how immorally the many prominent Roman Catholic leaders of the Third Reich acted, their standing as 'good Catholics' was never publicly challenged by their church’s leaders until defeat or death had denied these Nazi Catholics the power to do much harm"

As with Christian political hacks throughout its history, Hitler regarded some Christian leaders as competitors, others as supporters. That is exactly how it works in the United States currently among political hacks of the Christian persuasion.

Here is what Pope Francis had to say in defense of Muslim terrorists who murdered Charlie Hebdo staff in Paris on 7 January 2015, while other Muslim terrorists and devout supporters of the same hailed the event as a righteous blow in defense of Islam, the will of a sole and unique creator god:
"Pope Francis Declares That There Must Be 'Limits' To Free Speech In Criticizing Religion… On the papal plane, Pope Francis spoke beside Alberto Gasparri, who organizes papal trips. He used his aide in this analogy: 'If my good friend Dr. Gasparri says a curse word against my mother, he can expect a punch. It’s normal. You cannot provoke. You cannot insult the faith of others. You cannot make fun of the faith of others'… Pope Francis added that people who make fun of religion 'are provocateurs. And what happens to them is what would happen to Dr. Gasparri if he says a curse word against my mother. There is a limit.' "

That is not subtle. It is an incitement to violence as a means to suppress critics. When he got bad press, he sent out a Vatican lackey to claim that Francis did not mean what Francis meant:
"Vatican: Pope’s Charlie Hebdo Comments Didn’t Condone Violence... Francis in no way was supporting the Paris terror attacks, his press office says... “The pope’s expression is in no way intended to be interpreted as a justification for the violence and terror that took place in Paris last week,” Rev. Thomas Rosica... Rosica said the pope’s words about Gasparri “were spoken colloquially and in a friendly, intimate matter among colleagues and friends on the journey”... “The pope’s free style of speech, especially in situations like the press conference, must be taken at face value and not distorted or manipulated,” Rosica wrote"

"During the Second World War in Yugoslavia, Catholic priests and Muslim clerics were willing accomplices in the genocide of the nation[‘s] Serbian, Jewish and Roma population. From 1941 until 1945, the Nazi-installed regime of Ante Pavelic in Croatia carried out some of the most horrific crimes of the Holocaust (known as the Porajmos by the Roma), killing over 800,000 Yugoslav citizens - 750,000 Serbs, 60,000 Jews and 26,000 Roma. In these crimes, the Croatian Ustasha and Muslim fundamentalists were openly supported by the Vatican, the Archbishop of Zagreb Cardinal Alojzije Stepinac (1898-1960), and the Palestinian Grand Mufti of Jerusalem, Hajj Amin al-Husseini."

One of Francis' papal predecessors was a Nazi sympathizer:
"On October 19, 2014, Paul VI (Monsignor Montini) in a solemn ceremony at the Vatican is to be beatified which is the first step to sainthood. A miracle, the curing of an unborn baby’s illness, has been attributed to Paul VI. However, Holocaust Victims and their families from Eastern Europe who are locked in a decade’s long legal dispute with the Vatican over looted assets from the Second World War, question the saintliness of the man who as Vatican Secretary of State supervised the infamous Vatican ratline funded with Holocaust era loot."

"Ratlines were a system of escape routes for Nazis and other fascists fleeing Europe at the end of World War II. These escape routes mainly led toward havens in South America, particularly Argentina [home to Pope Francis], Paraguay, Brazil, Uruguay, Chile, and Bolivia..."

Similarly, Barack Obama believes that Islam can do no evil: "... no faith teaches people to massacre innocents. No just God would stand for what they did yesterday, and for what they do every single day... Today, the American people will all say a prayer for those who loved Jim [James Foley, beheaded by Muslims].... We keep in our prayers those other Americans who are separated from their families... May God bless and keep Jim’s memory, and may God bless the United States of America." – Barack Obama, August 20, 2014

Ditto for David Cameron: "David Haines was a British hero. The fact that an aid worker was taken, held and brutally murdered at the hands of ISIL sums up what this organisation stands for. They are killing and slaughtering thousands of people, Muslims, Christians, minorities across Iraq and Syria... They claim to do this [i.e., behead David Haines] in the name of Islam. That is nonsense. Islam is a religion of peace. They are not Muslims." – David Cameron, 14 September 2014

They and others would have you believe this:
Rule (1) Muslims cannot do evil.
Rule (2) If some Muslim does evil, see rule (1) above.
Do you believe it? Not me.
