The relationships in King Lear

I found myself very interested in this week's reading. I was extremely interested in the punishing of Gloucester. Cornwall and Regan mercilessly gouged out Gloucester's eyes somewhat ironically for treason;  both Cornwall and Regan are both treasonous on the grounds that they have abandoned King Lear. The servants in the household start to finally realize how terrible the sisters and their husbands are when Cornwall is torturing Gloucester. One servant tells Cornwall to stop and that he will fight to the death before he sees Cornwall gouge out another one of Gloucester's eyes. Then at the end of the scene, two more servants also state their dislike for both of their masters. It seems as if this is a foreshadowing of the ruin of the sisters and their husbands. I certainly do hope there is a blood bath at the end of King Lear, like the end of Shakespeare's Hamlet, to avenge all the wrongs done. I also feel a great amount of sympathy for Gloucester and Edgar. They are both in very tough situations in this part of the story. Edgar has agreed to lead his father to the cliffs of Dover, where he will apparently jump off killing himself. The pain felt by Edgar in leading his blind father to his death is I'm sure almost unbearable.  Gloucester is also suffering greatly physically from his injuries but also mentally because he knows he has wrongfully outcast his faithful son Edgar. The bonds between parents and children have become even  more important at this point in the story. Shakespeare is definitely trying to make people think about those people that are closest to us in our life and highlight the fact that some people are only there for us when they can get something in return, while some people will be there for us no matter what (like Kent). I believe from reading King Lear we all get a little helpful hint to re-evaluate our friendships and bonds and prioritize those relationships based on how truthful and honest those people involved are to us.
