You’ve established that already.
Your thesis should answer this question: Overall, what thought do you, iCeskate, have about what you’ve learned about torture? What do you notice about the phenomenon of torture? The rest of your paper should provide evidence to support that thought.
Use your brain and figure out what your thought is about what you’ve learned. If you have too many thoughts, pick one that is more important than the others. If you don’t have any thoughts, then revisit what you’ve learned or read up some more on your subject.
