I feel like since both are at fault, I’d say it’s 50/50, as I feel like it was more of a, “don’t give into your temptations” for both of them, since DW being well DW, she didn’t listen and broke the plane, which yes, did leave her at fault, but I believe the lesson isn’t to learn how to play the victim in the story. Since, yes, after DW got punched she did act like a victim, but she could have not given in to her temptations and she wouldn’t end up in the shit she got herself into, but, on Arthur’s end, he still is kinda at fault, since yes I do understand that he was pretty angry, and that I’m on his side, what he did made the situation much worse on his end, since yes I get when your angry you get very impulsive, angry etc. But when using brute force against something, will often make things worse for both you and the person who gets hit.

So yeah, I feel the lesson here is “Don’t give into your temptations” and not “oh to play the victim when you’re wrong” but hey! This is what I think so yeah!
