1. Would Neil still have committed suicide if Mr. Keating had never come into his life? Consider multiple perspectives here as you draft your group response.
Mr Keating was not responsible for Neal's suicide. And I believe that he would have commited suicide sooner if not for Mr Keating. Neil was unhappy with his father and life before his techer decided to enlighten him academically. His father was at fault.

2. Who was really the bravest of Keating’s boys? Who was a coward? Be explicit and support your answers.
Neil was the bravest, the boy with the res hair was the coward. He did not stand up at the end and was the first one to snitch . Neil was the bravest because he started the group. 

3. How did the poetry book make it into Neil’s room? (Did Keating put it there?) And if so, why, after telling the boys that the present administration would not look favorably on it, would Keating do that?

I thought that Neil had been reading it. I dont think Keating put it there, Neil was studying his lessons from Keating.
