Do I have this right?
It's upsetting, the very idea that some other person might be pretending to be a fictional character who ends the imaginary life of an imaginary creature in a subjectively problematic way...
(a lot of hypotheticals in there)
...as dictated by an ill-defined, ambiguous and hotly debated in-fiction moral framework which may or may not correspond to some degree to any of real-life, constantly debated, modern day, moral frameworks.
(that's pretty meta)
Not that it's nothing -- the idea that somebody else is doing that somewhere in the world right now -- but on my list of things to worry about, I would probably have to rank it well below this:
It upsets me that Batman -- whom I presume would be sane enough to reflect on the consequences of his actions -- keeps locking up villains in Arkham Asylum, from which they will inevitably escape to murder and torture mass innocents, and Batman never seems to learn from this, and if I were to complain about this on a comic book forum a lot of people would sound upset with me.
And even that I would rank well below:
A lot of people enjoy torture porn horror movies, and on purpose, they watch characters on screen being tortured horrifically, mentally and physically, and somehow this is a thing!
