How did Huck plot his own death?

After Huck's abusive father obtains custody of him, Huck realizes he will have to get away from him for good if he is to survive. His alcoholic father beats him, locks him up, and once, when drunk, chases him around the cabin with a knife. Huck knows he can't rely on the legal system to protect him, as they gave Pap custody of him in the first place. Therefore, he decides to take matters into his own hands and fake his death, then run away.
Huck happens to find a canoe floating down the river, in which he hides. When his father has gone, he saws his way out of the cabin. He puts supplies in his canoe. He shoots a pig, and then uses an axe to break down the cabin door. He spreads the pig's blood around and scatters some of his hair in it. He wants it to look as if somebody broke into the cabin and murdered him. He then hides in the canoe. When night falls, he heads for Jackson's Island. He barely misses his father's return, but he does successfully get away.
