Is helena a scheming person ?discuss with reference to the play

I think she is a scheming character but ends up doing the right thing. Helena Charles is Alison's best friend. She lives with them in their apartment while visiting for work. Helena is from an upper class family. She is responsible for getting Alison to leave Jimmy. She and Jimmy then begin an affair. Her sense of morality leads her to leave. She can be considered the play's moral compass.
