I see. Though I was trying to say that if we need to know what thoughts author actually put in his work, asking him would be the only way. It's not always necessary ofc, any of us can see different things in the same story, and may or may not use analogues with the real world.
For me it matters if the story, even in fantastic setting, was written just for fun, like GG, or was trying to make allusions with the reality or written under the influence of actual problems during that time period. For example, Fahrenheit 451 by Ray Bradbury was written under the influence of the paranoia brought by Cold war.
The writer was concerned, that mass surveillance and an attempt to eliminate communism empathizers among artists would do a lot of harm to further culture development.
That is why I can easily say that burning down libraries and supressing free thinking is wrong there, because these ideas were brought by the author himself, reflected the reality, and I generally agree to them.
And at the same if I read how Kendra, for example, destroys neutral towns, I will say, that killing is wrong, but still can try to find out what are her motives of doing this, that will not make me a fascist or a justifier of her actions. I don't need to compare it to S III Ohrdruf or something like that, there is no point.
