A college like Corpus Christi is a very small, close community. Many undergraduates will know virtually all the members of the JCR; live with them, eat with them, share a house or a corridor/staircase with them, share library facilities. Sports and social activities and dating pool might also be fairly confined to within this small group of your peers.
Imagine if after a drunken encounter, you were gossiped about and ostracised by your entire community. To leave is basically unthinkable as your entire existence was about being successful enough to get there in the first place. And your whole future appears to hang on you staying. But it’s awful. There’s no escape from it, you can’t see a way out or through.
I can understand why you might feel you had done something so heinous your life was not worth living.
The lad needed to be able to turn to someone, a mentor or pastoral support or personal tutor. I can absolutely understand why his shame prevented him from seeking that help.
It is awful.
The girl may have been justified in her actions trying to whip up a social frenzy against him and freeze him out. But I doubt he deserved death. And it was foreseeable that her actions could drive him to that point, because she would have known what it would be like to live every day with the weight of the misery of thinking everyone hated you.
So I’m afraid I do blame her. And I suspect, deep down, she will forever blame herself.
