What's the point with that quite lackluster story in Endwalker?

Then you are justifying genocide. Congratulations, you played yourself. I'm done with you.

It's fiction. None of it is real. The characters are pixels on a screen.

The attempts to try and portray people as 'wrong' or 'bad' for favouring darker stories in a video game are little more than the same sort of puritan attempts to try and declare that video games should be banned because they inspire violence.

If you, yourself, feel that you'll go out and commit genocide because a character you support in a video game did the same thing then fair enough. Personally I have more faith in people to not assume that because they join the Dark Brotherhood in an Elder Scrolls game then that is equal to advocating support for paid assassinations.
