How is Jed Parry dangerous in Enduring Love?

Discuss the signs of how, in the letter that makes up this chapter, Parry is becoming more threatening and hostile (chapter 16). The narrative of chapter sixteen shifts from being Joe’s rationalist mind to Jed’s troubled world views; it is told through a letter that McEwan crafted to show the reader the depth of Jed’s obsessiohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh- hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh- hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh- hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh- hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhn. At first glance, Jed seems to be harmlessly in love with Joe and although we see that in chapter eleven his love is more fantasy than reality, the reader struggles to grasp just how dangerous Parry could be. It is only until Jed feels truly rejected by Joe that he allows himself to feel and anger and coupled with his volatile mental state could cause some serious damage. After constant rejection from Joe that Jed misinterprets as simply trials from God, he is left with a bitterness that he tries to conceal beneath a biblical hatred, a wrath of sorts. Jed says in a letter to Joe that he “wanted to hurt [Joe]” for his denial of a God. This suggests to readers just how unstable Jed is; he has a severe mental illness and has hinted at suffering depression and loneliness throughout his life, therefore all he has to cling on to is the unconditional love of his personal God. At a time of high stress and anxiety, Jed transferred some of this love on to Joe and so the obsession began. God is Jed’s single lifeline as he has no friends or family, so when this is threatened by Joe’s beliefs he reacts violently and angrily. This shocks readers because up until this point Jed has maintained a bewildered, yet loving stance, promising that Jed and Joe can work through and resolve any differences so this sudden violent outburst comes as an unexpected surprise.
