I think that Marcos killed Ana for no reason and that is the point of the movie. I think he was in so much despair and uneasiness that he let all the repressed feeling one can have to control him. All his fears and disappointments became actions. I don’t think he loved her. Also I thought that Marco’s wife was interesting. We did not get to know her very well but I think she was far from linear. she had so much understanding of her situation that she was able to accept the role Marcos wanted to give her (furniture in the house) and she dealt with it.
