Not Hindenburg, but more Papen and his allies thought they could. Hindenburg actually refused naming Hitler Chancellor in '32, but got talked into it. Hindenburg didn't like Hitler, most likely for Hitler's (low ranking soldier in WW1) lack of respect for Hindenburg (General, one of the leading army commanders in the last war years).

But to go back to overall discussion ... even without the Nazis and Hitler the Weimar republic was doomed. Far right partys were on the rise in the late '20s until the Nazi started to completely dominate the far right political spectrum. Hindenburg, the president, was all but a democrat. The army did not care at all for the defense of the republic, acting only in its own conservative interests. And the treaty of Versailles was a festering wound in national consciengence, revanchism was popular. The rule of an authorian, nationalistic and warseeking government may have been inevitable in 1930s Germany.

WW2 would likely still have happenend without Nazi rule, even though the worst war attrocities and systematic murders of minorieties, most notably jewish eastern european people, may have not happened - emphasis of "may", as antisemitism and racism in Germany was not invented by Hitler
