I need help again with my English assignment . As it shows in the picture I need to make a 200 word essay if I would defend or prosecute the narrator.

Here’s what it says:
Imagine you are a lawyer at the narrator’s trial. How would you either defend him or prosecute him? Would you say that his actions indicate he is mad and not responsible for his crime or that, as the narrator says, the steps he takes to commit his crime show he is not mad and is responsible for the murder. Write an essay of at least 200 words that describes your plan in detail. Use quotations from the essay to support your ideas.

I’m desperately in need of help bro.
