The Wild Duck, Journal Four

I believe the characters that are at fault are Gregers, Werle and Gina. I believe Gina is at fault because she never told Hjalmer about what happened between her and Werle. If we examine Mrs. Sorby's marriage with Werle for exmaple, they are completely honest. They discussed each other's past and they plan on loving each other no matter what. Gina on the other hand, decided to hide the past. If she had told Hjalmer that Werle was making advances on her, Hjalmer might still have married her. But now, years later, Hjalmer is hurt by Gina. Hjalmer is hurt because he has believed a lie for 15 years and Hedvig is not even his child. Personally, I feel as if Gina had been open at the very start, these problems would not have arisen.
I also blame Werle for perusing Gina. We do not know if Gina was consenting to the relationship, but it was wrong of Werle to pressure Gina into a marriage. Werle valued his economic status over doing what was morally right. If Werle was a good man, he would have taken care of Gina and not forced her to marry off. Werle's actions of protecting his name over Gina show that he is also at fault for the ordeal.
Lastly, I also blame Gregers. Gregers was not involved in the affair, but he was the one that brought darkness to Hjalmer's life. Technically, Hjalmer could have lived the rest of his life unaware of the truth. Instead, Gregers followed what he believed was morally correct and exposed the truth. It it weren't for Gregers, Hedvig would not have to sacrifice the wild duck, Hjalmer would still be happy and they would live on as a happy family.
The only character I view as being completely fautless is Hedvig. Hedvig is innocent and does not understand what is happening. Hedvig had no control over Gina's actions and she as well is blind to the truth. In Act Four, Hjalmer shows aggression towards Hedvig, showing that he does blame her, but in reality, she in the only innocent character in the play.
So far in Act Four, no characters have taken responsibility. Hjalmer seems to be placing all the blame on Gina. If anything, Hedvig is the only character showing any feeling of responsibility. She even begins to blame it all on herself.
