Final answer:
The McCandless family dynamics may have pushed Chris away due to high expectations, unresolved issues, and the influence of Thoreau's philosophy.
Step-by-step explanation:
The McCandless family dynamics in chapters 11 and 12 may have pushed Chris away due to various underlying causes. One piece of evidence comes from the book Into the Wild by Jon Krakauer, where it is mentioned that Chris felt suffocated by his parents' high expectations and their materialistic lifestyle. This is evident when Chris donates his college fund to charity and chooses to live a minimalist life in Alaska.
Furthermore, in the same book, it is revealed that Chris had unresolved issues with his parents, especially his father. Chris felt betrayed by his parents' dishonesty and their lack of support for his dreams and ideals. This strained relationship likely contributed to Chris's desire to distance himself from his family.
Another source of evidence can be found in Henry David Thoreau's book Walden, which shares a similar theme of dropping out of society to live a meaningful life. Thoreau's philosophy of self-reliance and non-conformity may have influenced Chris's perspective on family and the societal expectations placed on him. This can be seen in how Chris sought solitude and independence in the wilderness, away from the constraints of family and societal norms.
