So it's a fantasy? What the quote essentially says is 'being a good person is cool and all but that doesn't really matter to assholes' and it's generally preferable to know things like murder is meat and golden years tarnished black and not need them than to encounter a situation where you want them but don't have them. No one is a good person all the time especially irl.
Honestly the white council probably abide by this, they're basically the good guys but if you break their rules they'll fuck you up.
Your trying to make a point here, and its a good point. And one that we should definitely keep in mind. But your arguing it very badly.
Heres an example of them being ruthless and pragmatic.
Anti-Hero: The White Council is frequently forced to do hideous things in the name of the greater good, such as ordering for sixteen-year-old kids to be decapitated for partaking in
Black Magic.
Here is an example of... Captain Anastasia Lucio being genuinely heroic and noble. Even if it costs them.
The Needs of the Many: Averted in
Dead Beat, she and her patrol of Wardens are working to stop the Darkhollow from being complete when they discover a group of children trick-or-treating and about to be attacked by zombies. They can either let the kids die and work on saving everyone by stopping the ritual, or potentially let the ritual go off and protect the children. Luccio chooses the latter and is angered Harry would think she would do otherwise.
The white council is a tapestry of compromises, broken promises, and people who go to far.
But they
are the good guys, they
are trying to the right thing, and they
are trying to help.
Mollys own family is also an example of genuinely, honestly good people being able to make a positive difference in the world. Molly has every reason to frown on the kind of dismissive cynicism that crops up in prince, and in hell's in general. And if anything being able to look at a demon and tell them "thats bullshit"
will help us.
Being a good person is roundly dismissed and probably mocked by people like the Denarians, demons, monsters like faeries and the winter court. Fuck them I would be glad to throw out any advice they give us.
And being a good person
really does matter to the people we actually care about. Like Our Family, Harry, and the angels who are gonna be hanging around when our dad retires. They think it matters, and they show it does fairly often. The far reaching effects of Harrys actions do really change peoples lives for the better, and so can we.
You
wanted to make a point about
being clever, and not playing fair Nor expecting fair play from enemies who have every reason to ignore the rules.
But you quoted a shitty, smarmy asshat saying "Ha-ha! Look how dumb all the good people are! Point at them and laugh!"
Also we don't have a binary choice between. "learn evil powers or don't learn evil powers." Its a scale of prioritization.
The time we spend learning to send souls to hell to be flayed alive for all eternity is time spent not learning to make artifact weapons, learning to cure cancer, learning to teleport, or learning to block bullets with our winning smile. Which is entirely beside the point, but still annoyed me.
