Characters that are well written are extremely complex, just as people in real life are. And just like people, characters will be slightly different depending on the situation in which they are placed.
For example, if a character is serious while inside a church, we might perceive this character as thoughtful, respectful, traditional or religious. However, if the character is in a party, we might perceive the same behaviour as something that a shy or awkward person would do. Although the character has not changed, the variety of setting can make us perceive them differently.
An easy example can be Hamlet. Some directors of the play put him in the setting where the ghost is real and played by another actor. Others put him in a setting where the ghost is played by the Hamlet actor giving off the impression that he is insane. These are two different settings for the same character and create completely different images. Use this paragraph as a starting point for your essay.
humans point of view are all different depending on the person you are. some people see the world as a miserable place where nothing can live, others see it as more areas to conquer, then there are some who just don't really care. its not about how people see it, its about how they shape it and act on it.
