"Roger Chillingworth's main objective is to revenge upon Dimmensdale and not redeeming himself by helping Hester." Is this a good thesis statement?

"good" is in the eye of the beholder.

What I wonder is where will you get evidence for this conclusion.

You have not written a thesis statement. You have written a statement of fact, and they are not the same.

Your thesis statement must include factual information plus your position/opinion/stance. Without your position on the topic, it isn't a true thesis statement. So think of this sentence as the angle you want to take on the topic and what you intend to prove by the end of your paper. (If your statement is simply factual, then there's nothing to prove!)

This is one of the very best places I've seen online to help students write good thesis statements. It shows you sentences that aren't thesis statements and how to turn each one into real thesis statements.

To write this, you must be able to state your own opinion/position/stance on the topic. Once you've drafted a thesis statement, feel free to post it if you'd like someone here to check it.

Determining whether a thesis statement is good or not involves evaluating its clarity, relevance, and supportability. In the given thesis statement, "Roger Chillingworth's main objective is to revenge upon Dimmensdale and not redeeming himself by helping Hester," it appears to be clear and specific. However, it is important to note that the spelling of "Dimmensdale" might be a typo, and the intended name should be "Dimmesdale," which is a character from Nathaniel Hawthorne's novel, "The Scarlet Letter." Assuming this typo, let's break down the statement and see if it meets the criteria:

Clarity: The thesis statement is clear in identifying Roger Chillingworth's main objective, which is to seek revenge on Dimmesdale rather than redeeming himself by helping Hester.

Relevance: The thesis statement is relevant as it focuses on Roger Chillingworth's motivations and objectives in the novel, specifically regarding Dimmesdale and Hester.

Supportability: The supportability of this thesis statement depends on providing evidence from the novel, such as Chillingworth's actions and behaviors throughout the story, his interactions with Dimmesdale, and his lack of efforts in assisting Hester's redemption.

Overall, the thesis statement seems reasonable and has the potential to be effectively supported with evidence from the novel. However, it is important to analyze the specific textual evidence and arguments to ensure a compelling and comprehensive exploration of Chillingworth's motivations in "The Scarlet Letter."
