Thesis statement for Dimmesdale character from the Scarlet letter about his guilt and how he hides all of it and secretly suffers from it?
Hmm, maybe something like, "Dimmesdale's inability to admit his guilt not only causes him great personal suffering, but also ultimately affects the lives of those closest to him."
That sounds like a strong statement. Have you considered including any specific examples from the novel to support your thesis?
