As I Lay Dying by William Faulkner:
Sometimes I aint so sho who’s got ere a right to say when a man is crazy and when he aint. Sometimes I think it aint none of us pure crazy and aint none of us pure sane until the balance of us talks him that-a-way. It’s like it aint so much what a fellow does, but it’s the way the majority of folks is looking at him when he does it.
Because Jewel is too hard on him. Of course it was Jewel’s horse was traded to get her that night to town, and in a sense it was the value of the horse Darl tried to burn up. But I thought more than once before we crossed the river and after, how it would be God’s blessing if He did take her outen our hands and get shut of her in some clean way, and it seemed to me that when Jewel worked so to get her outen the river, he was going against God in a way, and then when Darl seen that it looked like one of us would have to do something, I can almost believe he done right in a way. But I don’t reckon nothing excuses setting fire to a man’s barn and endangering his stock and destroying his property. That’s how I reckon a man is crazy. That’s how he cant see eye to eye with other folks. And I reckon they aint nothing else to do with him but what the most folks say is right.
