Medieval and early Renaissance Christian theology tended to consider the Jews in quite a negative light... and esoteric Judaism even worse. Likewise, it was considered that the ultimate sin was to try to do "what only god can do: create life." Creating golems was explained in some Christian contexts as animating clay or the dead with summoned and bound demons. In others, simply hubris and a false life that naturally became corrupt because its creator was inherently flawed by being human.
The Jewish tales of Golems are not all sweetness and light, either.
Medieval Jewish stories are, as cited by Professor Jeremy Dauber, Atran assistant professor of Yiddish language, literature, and culture at Columbia University, as often having the golems turn evil when not used solely for the defense of the people, but for mundane tasks. He cites several variations... and avoids drawing the comparison to Frankenstein's flesh golem, Adam.
Frankenstein's Adam, misunderstood, and misrepresented in 20th C films, was posessed of no malice, merely ignorance and incompetence, plus great strength. And is put to death for mistakes... The real monster is indeed Frankenstein, but Frankenstein isn't the golem in the novel.... Adam isn't the standard Jewish golem, either - being a flesh golem, not a clay one, but his creation is what made Dr. Frankenstein the truly evil being, for his flawed creation and his hubris that he could succeed well.
Add to that 50+ years of golems as movie monsters based loosely upon both Jewish Golem-Turned-Bad and widespread Christian hatred of attempts to create life...
