The thesis is quite strong in its content and its application to Homer's work. His depiction of the gods is akin to how one would view mortals, while some of his mortals (Hektor) might resemble immortality. I think that the thesis statement is quite strong. The word "motifs" strikes me as the one word that might be reconfigured. It conjures up images that, at least in my mind, detract from the content- driven nature of the statement. In replacing "motifs," I think a word which focuses on the the second half of the statement as opposed to the first might be the most desirable option. For example, "Throughout the expression of anger, revenge, and sorrow..." might allow a greater sense of understanding to the thesis statement.
