knowing what kind of risk he is taking, why do you think Mcmurphy still goes forward with planning the party on the ward?

The party is everything that nurse Ratched despises. It would also be the ultimate victory for Mac over the nurse. On a deeper level Mac wants these men to behave like normal men, for the first time in their lives. He wants Billy to have sex and he wants to see his friends smile like human beings.

Thank you.
