expensive long guns in the world. The Damas version of their over-and-under shotgun currently sells new for more than $165,000. The fact that Rainsford can afford to have one of those guns shipped to his hunting destination shows that he isn't hurting for money.

We can also infer that while he is a very good hunter, he isn't an exceptionally deep thinker. He scoffs at the very notion of animals having feelings. I also think this quote shows that Rainsford isn't capable of much empathy either:

"Don't talk rot, Whitney," said Rainsford. "You're a big-game hunter, not a philosopher. Who cares how a jaguar feels?"

Finally, I think it has to be said that Rainsford isn't somebody given to panicking, and he is still capable of creative and logical thought even in the midst of an incredibly stressful situation. This is what makes him so fun to hunt for Zaroff, but it is also why Rainsford is able to survive the entire encounter. Each of these inferences serves to round out Rainsford as a much fuller and more vibrant character.

The Honorable Zaroff.  Despite the barbaric intent of General Zaroff's desire to hunt human beings, he still displays a sense of honor and chivalry that he must have maintained from his military days. When he announces that he plans to hunt Rainsford that night, Rainsford wonders what he can expect if the impossible happens--if he wins.

     "I'll cheerfully acknowledge myself defeat if I do not find you by midnight of the third day," said General Zaroff. "My sloop will place you on the mainland near a town." The general read what Rainsford was thinking.
     "Oh, you can trust me," said the Cossack. "I will give you my word as a gentleman and a sportsman..."

Rainsford probably does not believe Zaroff, but I had an inkling that the rules of the game would be even more important to the Cossack than the actual victor. Sure enough, when he is surprised in his bedroom by the very much alive Rainsford, Zaroff "made one of his deepest bows," and announces that Rainsford has "won the game." It is Rainsford who breaks the rules, claiming that he is "a beast at bay," and the hunt continues.

Rainsford the Soldier.  Rainsford's war service is never directly discussed, but a single allusion suggests that he was also a World War I veteran.

     Rainsford had dug himself in in France when a second's delay meant death.

It suggests that he was not just a killer of animals, but a former soldier who could defend himself and kill another man if necessary.

Rainsford the Killer.  We don't know for certain that Rainsford killed Zaroff, but it can be inferred that he had reverted to a savage himself by the final line of the story:

     He had never slept in a better bed, Rainsford decided.

How else could Rainsford had slept so comfortably if Zaroff had not been disposed of?

To write a full character analysis, it's important to know how writers accomplish characterization. They do it through:

• what the character does
• what the character says
• how the character is described
• what other characters say about the character

In terms of writing a character analysis in "The Most Dangerous Game," it will depend on whether you're writing about Rainsford or Zaroff.

A topic sentence for a character analysis of Sanger Rainsford could read something like this:

Because Sanger Rainsford is able to control his fear of being killed by a madman and rely on his intelligence and the experience he has gained as a hunter, he ultimately prevails.

A topic sentence for a character analysis of General Zaroff could read something like this:

Despite the obvious advantages he has over Rainsford, such as knowing the geography of the island, possessing tracking dogs and superior weaponry, General Zaroff's overconfidence and arrogance prove to be his undoing.

I'm guessing your question concerns "The Most Dangerous Game" since that is the group your question is posted under.  The wording of your question is a bit confusing.  Do you mean three EXAMPLES that support the THEMES of the story?   I know cruelty and violence are themes in the story and in terms of topics that support it, I would assume you could consider instances, or situations, in the story which lend themselves to evidence these themes.  One could be the two men and their lack of compassion for their prey, as seen in Rainsford in the opening scene when he plainly states to Whitney "Who cares how a jaguar feels" when asked to consider his prey, and then by General Zaroff when he shows his primary concern is in dealing with a "worthy opponent", namely humans. 

Hope this helps!  Please rephrase your question to clarify what it is you need. The terms "topic" and "thesis" are rather confusing.

I think that this depends some on what interests you about this story.  If there is some aspect of it that really interests you, you should write about that.

I think one thing you could write about is whether Rainsford is going to end up taking over Zaroff's set up on the island.  Is he going to start hunting people?  You could look for stuff in the story that seems to say one way or the other -- stuff that tells what kind of a person he is.  I'd write a sentence that looked something like this.

In this story Sanger Rainsford is no better than General Zaroff.  I believe that he will take over from Zaroff and start hunting people himself.
