Because in the late twentieth century, you couldn't seriously ask other people to think that you believed in honor and truth, and the purity of the body, the defense of women, the sanctity of true love, and all the rest of it. But apparently, Andre really had believed it.
In the late twentieth century, societal norms and expectations made it difficult for individuals to express belief in traditional values such as honor, truth, and the sanctity of love. The prevailing attitude was one of skepticism, where openly espousing such ideals might lead to ridicule. Many chose to hide their genuine feelings in favor of a more cynical view of reality.
However, the character Andre stands out in this context, as he seems to genuinely hold onto these ideals. This contrast highlights the struggle between maintaining personal convictions and conforming to modern skepticism, suggesting a deeper exploration of authenticity in personal beliefs amidst a changing cultural landscape.
