I'd much rather take that over ignorance. "you have no enemies" is a false, idealistic statement. Thorfinn doesn't understand that, and drags down his entire community because of it.
Uh no, you are the one that don't understand anything lol as if you just started with surface politics and said "that's it", and fine with the status quo.
"You have no enemies" is not something that Thorfinn just randomly picks up on someday like some internet users. It was from his father and Thorfinn hated the f out of it for years, he thought that was one of the reasons that made his father die, he too DID THINK it was unreasonable and idealistic lol. But when he finally understood and accepted the saying, he did not change and think it's "reasonable and realistic", he literally still thinks it the way it is, but he does not want to give up on it just because of that. Re-read the farm arc lol.
"You have no enemies is so idealistic". That's literally the point and make this series stand out and viral lol. They challenge the unrealisticness, the impossibility. And you for sure know it's a work of humans because of it, humans find purpose of life in these sort of things. But the series does not just end with blindly chasing these things because we still have
Canute and the rest of the world following the realistic methods juxtaposed with it, making the audience acknowledge of those realistic methods, adding more insane curiosity for the result of that idealistic path.
Canute's way or Thorfinn's way, it both dragging other people down for it. Because their goals are peace, and peace is a luxury thing that's not easy to achieve. But Canute's way is hella much more brutal than Thorfinn's and has people die like, everyday. So yeah, not a fan.
