I find Se7en an amazingly good movie, but among its weaknesses is the Envy killing. I found the justification for it very unconvincing, as if forced into the story, just so we can have the (iconic) something-in-box scene. Not being a psychologist, John Doe doesn't strike me as a guy who would get jealous, especially for something so petty. Is there something I'm missing?
Not sure how an isolated, mentally challenged, psychotic can't envy the life of a simple man?
Often geniuses become insane and often wish they were more simple. The saying "ignorrance is bliss" definitely came from somewhere.
So what would be wrong with John Doe envying the life of a simple family man? I thought it was brilliant.
There is another weakness. After all the well-planned murders to prove his point, he involves for the last two people, who recently moved in the city: Mills and his wife. Doe couldn't possibly have known about this.
I have two theories explaining this. First: Doe got under pressure after the police caught his trace. He had to switch plans, so the last killings were planned under pressure and not perfect. Second theory: He always planned the wrath involving the policeman going after him. He planned that after the first murders some detective will catch his trace. But to enrage him, he needed to hurt him really bad. So he planned to use the wife of whatever detective it will be. To match the scheme it had to be the Envy-murder, but as it had to be improvised. So it lacks the perfection he tries to achieve.
