Well, in a fictional and very dark context, it could potentially be about revenge. If a woman has been severely wronged by a man in the story, perhaps in an extreme and misogynistic way, she might be depicted as taking this drastic measure out of extreme anger and a desire to cause the ultimate harm. But this is a very disturbing and unethical concept.
Another possible, though extremely dark and unacceptable, motive could be related to some form of extreme ideology. Maybe in a fictional dystopian story where there are radical and immoral beliefs, a woman could be portrayed as doing this as part of a larger, sick ideology. But again, this is just in the realm of very disturbing and inappropriate fictional ideas, and has no place in real - world values.
Power. In a fictional world where power dynamics are at play, a woman might see castrating a man as a way to gain complete control over him. By taking away his masculinity, she could be aiming to subjugate him and assert her dominance in a very brutal way.
It could be for comedic effect. Writers often use absurd situations to make people laugh. So, the idea of a woman putting a man in a washer is so outlandish that it can bring a lot of humor to the story. Another motive might be to show the woman's dominance in the relationship in a very extreme and funny way. In some stories, it can be a way to turn gender roles on their head.
I'm not aware of any 'famous' works specifically about this extremely disturbing and unethical concept. Such a topic involves extreme violence and goes against basic human rights and ethics, so it is not a common or acceptable theme in mainstream literature or art.
Perhaps she has some sort of control issues. By hypnotizing her husband into this state, she might feel like she has more power in the relationship. It could also be a very strange form of role - playing for her, where she wants to experience a different kind of dynamic in the relationship.
Maybe he was a bit of a do - gooder in a very wrong way. He saw what he thought was a woman in distress and his sense of heroism kicked in. He didn't consider that there could be something supernatural or dangerous about the situation. He just wanted to 'save' her from the tree.
One possible motive could be madness. Maybe he had lost his sanity long ago and the sight of the woman in the tree was just another object of his deranged actions.
There could be several reasons. He might have misinterpreted the woman's actions as a threat, even if they were not. Since his mental faculties are impaired, he may not be able to accurately perceive social cues. Another possibility is that he was in an over - stimulated or agitated state and lashed out without meaning to kill. It's also possible that he was acting on some basic instinct without the ability to think rationally about the situation.
In some cases, it could be a desire for revenge. Maybe the woman feels wronged by the person she is stalking in some way, like if she was rejected or humiliated. So, instead of handling it in a healthy way, she chooses to stalk as a form of getting back at them. It's really a complex and concerning behavior that often has multiple factors at play.
One possible motive could be robbery. He might be planning to use the knife to threaten the occupants of the house and steal their valuables.
His motives could be power. He might want to rule the land of stories.
