But thats ok becasue there are a bunch of other things to confuse oneself with instead!
For example, Quentin. He's just one big ball of confusing. Faulkner did a birlliant job of describing his gradual slide into madness, so much so that even as you're repulsed by Quentin's thoughts, they make complete sense in some twisted way. Qunetin's failed suicide pact with Caddy is one such example. There's a sense of horror as Quentin contemplates killing his sister to free her, and his family, from the decisions she's made, but at the same time, there's maybe a little logic in there. Or at least, that little crack where reason could potentially fit is visible to the reader.
Quentin's obsessed with Caddy He wants to save her, is desparate to do so, but he can't. He can't handle this "can't".
So now he's going to kill himself. It's the logical next step really. Well, not really, but Quentin's been losing his grip on everything for a while. His family, and world, is falling appart, and his desparate focus on these events have only made the situation worse in his head, to the point of no return.
Becasue it's aparent in Benji's chapter that Qunetin had died, it becomes easy to realize how he does so as his mental deterioration becomes more and more obvious. The weights he buys, the sickeningly calm demeanor, Quentin's ever preset obsession with time even as he throws it aside as useless; when it becomes clear what exactly is going on it's too late. Not just for Quentin either; it would appear the entire Compson family is spiraling.
