Obsession
Genuinely everything in this movie happened because he didn't know how to talk with women if he had fumbled her and moved on naturally and not forced her to like him he wouldn't have felt like he didn't earn a her love which wouldn't have led him to needing the love of a woman that's natural without any outside interference like a one wish willow
Yes he is the villain in this movie there is no doubt about that he should be dead or in prison for his actions
But the idea that you can apply this to real life is fundamentally a flawed critic against men you can't apply the actions of a man that's not possible to replicate in real life to men in real life
