Tell me how i can fix this body paragrapf for a critical lens essay, and what i need to add?

The novel “night” shows the quote “ All that is necessary for the triumph of evil is that good men do nothing” is true throughout the whole book. This quote is proven through the theme during the book. Theme is the central message revealed through a literary work. The theme of “night” was to try and show people how much people suffered during the holocaust just because there was no one willing to help. This is also evident in the quote because the quote says that “if good people do nothing to try and help then evil wins.” You must always keep in the back of your mind that if you know someone needs your help, you must be willing to make a sacrifice for them. Do not just sit back and do nothing just because it’s not happening to you.
