Why is Anse so Transfixed on Bringing Addie Back To Jefferson?

The only clear goal a hundred pages into As I Lay Dying  is for Addie to be buried in Jefferson. Anse is disregarding everybody's advice and going to extreme lengths to find a way to transport Addie to Jefferson. Characters such as Tull comment how Anse has never been this motivated in his life and something has changed. I believe that Anse is so motivated because he did something terrible to Addie in her past. This comes from a comment Tull made,"Wherever she went, she has her reward in being free of Anse Bundren."(Faulkner, 59) Addie made the wrong decision. She regretted marrying Anse and I believe tried to get out of the marriage or she cheated. I believe this because she wants to be buried no where near Anse, but with her parents. Anse did not allow Addie to leave so she was stuck in some sort of hell where she had nowhere to go. After Addie's death, Anse is filled with regret for his actions and believes that bringing Addie back to Jefferson is a way to atone for his sins. I think the kids have some idea of this because Jewel rides on a horse alone when attempting to make it back to Jefferson. This would also explain why Jewel was Addie's favorite; Jewel knew what hell Addie was going through. In conclusion, Anse is so intent on bringing Addie back to Jefferson as a way to atone for his actions that he committed during their marriage.
