How does Twain use sentence structure in the following passage to emphasize the point of view and characterization of Huck Finn? "Everybody was willing.... never mentioned again by the gang, but have a curse put on it and be forgot forever."

“Twain realized on finishing The Adventures of Tom Sawyer that Tom ‘would not be a good character’ for the first person narratives to come…Tom is indeed a different person in Huck’s eyes than in Twain’s but point of view accounts only in part for why Tom changes from an exuberant mischief-maker to a self-centered tyrant (almost a caricature of his earlier self) after The Adventures of Tom Sawyer. The shift reinforces [the] implication that Tom is becoming a typical St. Petersburg adult, hypocritical and proslavery.”

"Everybody was willing. So Tom got out a sheet of paper that he had wrote the oath on, and read it. It swore every boy to stick to the band, and never tell any of the secrets; and if anybody done anything to any boy in the band, whichever boy was ordered to kill that person and his family must do it, and he mustn't eat and he mustn't sleep till he had killed them and hacked a cross in their breasts, which was the sign of the band. And nobody that didn't belong to the band could use that mark, and if he did he must be sued; and if he done it again he must be killed. And if anybody that belonged to the band told the secrets, he must have his throat cut, and then have his carcass burnt up and the ashes scattered all around, and his name blotted off of the list with blood and never mentioned again by the gang, but have a curse put on it and be forgot forever."
