Let's have a discussion. what defines a well-written character? what your answer should contain: a reasonable and logical response that isn't biased towards personality traits or any specific writing genre. what your answer shouldn't contain: a minimalistic, biased answer. for example "i think a good character should be smart." good and bad character examples are appreciated.

A well-defined character is often considered a protagonist or dynamic person. Someone who can change for better or for worse, and hold onto their values with religious loyalty. 

Good character example: Rosalind in Shakespeare's As You Like It. She is a true character who sticks to genuine and moralistic expectations of the society around her, while helping others advance their ideas of love.
Bad character example: Tom Buchannon from The Great Gatsby. He's rigid and a static character. His selfishness ultimately earns him a lack of trust in Nick and a torn marriage.
