1.) Who do you think had the most power throughout the play-Proctor, Abigail, Judge
Danforth, or Putnam?

I think that Abigail held the most power because she is the one that drives the whole play.  She makes up the rumors and puts the blame on others/accuses them of witchcraft.  She as the antagonist of the play is driven by her desires for Proctor and this makes her want revenge on others and make them suffer as well.  And in the end Abby got innocent people killed for her actions and was never blamed.
