The tear on Wormtounge's cheek, is purely because he is overwhelmed by Saruman's forces - and positively so - there is no sorrow here for the world of Men from Grima. But we've discussed this tear quite a lot in this forum so I won't go too indepth into it, LOL!!!!

But since it still belongs into this thread I can't resist to comment on it.

I am of opposite opinion. Surely he is awed: He sees an Uruk army which he didn't think was possible to exist.
But then he realises what this force is able to do - and destroying Rohan and its people to the very last child must have looked far better on paper. I don't even think Grima thinks about Eowyn in this situation (Saruman might have told the Uruks to spare her), it's just that all of a sudden it strikes him what Saruman's plans might look like if put into reality.
All we have to argue with is his facial expression which we see for mere seconds so it's really few, but this is how I interpret it.

The second thing is, that between now and Grima killing Saruman in the movie we will only get to see him one more time, when Isengard is flooded. If the moviemakers didn't get at least a glimpse of character development into Grima at this time, his killing of Saruman would have been completely unrealistic.

Third, Grima just isn't an overjoyed Nazi in the book, as we see especially in "Many Partings". Though this, of course, is a bad argument for the movie.
