This is also an interesting viewpoint. Both Mary and Henry are portayed as being evil whereas Fanny and Edmund are good. And it is interesting that Mary appears to be the more "evil" of the two. I'm trying to look at the idea as objectively as possible.

But the more I think about it, it is true that Henry's motives are very clear and open, whereas Mary's are not always open to us. Henry likes to go around breaking hearts, which is not very commendable.

But Mary wants to get Edmund to marry her, and get him to change his profession against his will because she's money oriented, and she's trying to befriend Fanny, apparently with an ulterior motive that is unknown to us (probably just to be close to Edmund?). She has an apparent joy in collaberating with her brother in his plot to get Fanny to fall in love with him, which I don't quite understand.

I can at least understand Henry's wish to get a woman to fall in love with him, even if I can't condone it, being as dishonest as he is. But what motive does Mary have to collaberate in such an effort?
