3- a- what did Ben Ross decide to do when got out of hand ? b- do you think he did the right thing ? c- what would you have done in his place ?

Ben decides to have a final wave rally to unveil their true leader (Hitler) in order to bring home his point and end the wave. I think this was rather dramatic but perhaps fitting given the scope of the experiment. I don't think I would have started the experiment in the first place.
