Answer:
While Hitler was making several references to killing Jews, both in his early writings and in various speeches during the 1930s, it is 100% certain that the Nazis had no operative plan for the systematic annihilation of the Jews before 1941. The decision on the systematic murder of the Jews was apparently made in the late winter or the early spring of 1941 in conjunction with the decision to invade the Soviet Union.
The primary attribute of the characters in morality plays reflects the fact that these plays were naive allegories is the fact that the characters are often very simplified.
This should be true. Scientists very often have the idea of self-censure because they understand whether or not their research could be potentially dangerous, for example, if they understand that their creation could be a terrible weapon they decide to not pursue it and abandon the research. Things get nasty when they don't do it, but almost anything can be exploited so they sometimes don't even understand in what ways their research could be exploited. If ideology starts banning scientific research because of ideological differences, then it's similar to how the church killed scientists in the medieval era because scientists opposed what was essentially ideology at the time.
