So, thanks for the help to those who answered my last question. My book is Murder on The Orient Express by Agatha Christie, and I need a thesis for it. In the book, a man is murdered by a grieving family, because he killed their daughter. I want to do my research paper on how not all murders are justified. Is that good enough to help me with my thesis statement?

You have stated a fact, not a thesis.

Your thesis statement must include factual information (which you already have) 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.

Ok, you are now using "justified" instead of "legal"

There is a big difference in those terms. Justified by whom, God? The gulf between morals (right and wrong) is vast when compared to legal (crime or not).

If you are arguing morality, now law, you can have an opinion on that pretty easy. Such as: Tall girls should not be allowed to play volleyball because it is patiently unfair and excluded Japanese girls, who are generally shorter.

If you are looking to the rules and law, your opinion has to be different: Tall girls may have an advantage over short girls, but we need to change the rules to not let tall girls dominate the entire team.

Yes, your topic of exploring how not all murders are justified is a valid and intriguing thesis statement for your research paper on "Murder on the Orient Express" by Agatha Christie. However, to create a strong thesis statement, it would be helpful to refine and narrow your focus a bit further. Here's a step-by-step guide on how you can do this:

1. Determine your stance: Decide whether you want to argue that no murders can be justified, or if there are certain circumstances in which murder might be seen as justifiable.

2. Review the book: Carefully analyze the events and characters in "Murder on the Orient Express" to identify instances or characters that exemplify the theme of justifiable or unjustifiable murder. Think about the motivations, moral dilemmas, and consequences portrayed in the story.

3. Select your main points: Choose two or three key examples from the book that highlight the different perspectives on justifiable murder. These examples will serve as the main points of your paper.

4. Formulate your thesis statement: Based on your selected main points, craft a strong, concise thesis statement that clearly presents your argument. Example:

"In 'Murder on the Orient Express,' Agatha Christie explores the complex moral dilemma of justifiable murder, ultimately demonstrating that while revenge may fuel a desire for justice, the act of taking a life can never truly be justified."

Remember, this is just an example, and you should customize it to fit your specific arguments and ideas. Your thesis statement should provide a clear roadmap of the main points you will discuss in your research paper, and it should reflect the unique perspective and focus of your analysis.
