Another motive could be the build - up of years of emotional abuse. She might have felt so trapped and hopeless that killing him seemed like the only way to end her misery.
One possible motive could be severe mental illness. For example, if a woman is suffering from postpartum psychosis, she may experience hallucinations or delusions that lead her to harm her children. Another motive might be extreme desperation. If a woman is in an impossible situation, like being trapped in a very abusive relationship and seeing no way out for her children, she might make this tragic choice. However, these are just some of the possible reasons and each case is complex.
Well, in the short story, it could start with showing the woman's daily life filled with fear and oppression from her husband. She might have tried to seek help but failed. As time goes by, she realizes that the only way to end her nightmare is to take extreme action. So she kills him, and then the story could explore her feelings afterwards, like guilt, relief or a mix of both.
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.
Revenge could be a motive. Maybe she was wronged by someone in the past, and she disguises herself to target those related to the person who wronged her.
One possible motive could be betrayal. If someone she trusted, like a partner or a friend, deceived her, she would want revenge. Another motive might be envy. If someone took something from her due to envy, she would seek revenge.
One possible motive could be love gone wrong. If she was betrayed by a lover, her revenge would be a way to cope with the heartbreak.
Motive can also be about self - discovery. A woman might be seducing another woman to explore her own feelings and boundaries. Maybe she has always been curious about same - sex relationships and uses this 'seduction' as a way to understand herself better. Also, it could be for companionship. Some women feel more understood by other women, so the'seduction' is a way to create a closer, more intimate companionship that they may not have with men.
Maybe she was abused by him and couldn't take it anymore. Or he was cheating and she snapped.
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.
It could also be a personal vendetta. Maybe she had some sort of conflict with someone in the past, and that person decided to kidnap her as revenge. For example, if she had testified against someone in a court case, the person might want to get back at her.
