That was an era, from what I understand of it, that saw religious corruption all over the place. Hitler was, in fact, a Jesuit (there's even a picture of him working with the Antichrist, the Pope, according to historicist opinion). The National Socialist era of Germany (Nazism) is the same as Zionism and Communism, all created by the Jesuits. One more note on the leader of the Third Reich, he was actually a Khazar (He was in the Rothschild line through someone else).
Fun Fact about this: WWII was the second spirit unto frogs, as talked about in Revelation 16. Both WWI (the first spirit unto frogs) and WWII were about pushing the Khazars (Jews by religion, but Turkish by blood) to Palestine to set up a Nakba, according to the Balfour Declaration.
All this is to say yes, there can be some connections to the Salem Witch Trials. Part of the issue some people have with the Holocaust narrative is that some Khazarian actors did such a good job convincing people that it happened, one person named Germar Rudolph wrote a book exposing the actual history of it the Jesuits don't want us to know about it (and their Zionist agents as well, by the way).
