You're right as far as the book goes, but I really think this is a 
plot hole by JKR. It seems to me that spell casting requires 
concentration and thought (see the Lexicon for more on that), and it 
really bugs me that someone can cause another to cast a spell. Look 
at it this way: if someone was holding a gun to your head and making 
you do something bad, even if you're totally trained to do it, you're 
not going to do a good job. Your hands will shake, you'll drop 
things, etc. Especially if it's complicated. 

And if they totally controlled their mind and made you cast that 
spell, isn't it *them* that is casting the spell, and not you? 
Because you can't concentrate to cast hte spell, you're Imperio'd!

It really seems wrong that someone can Imperio to cast a spell. 
Simple actions, yes, but casting curses? I just don't buy it.
