I think you need to pay a little less attention to how he acts, and focus on what they all do. It really annoys the heck out of me. Cloud is going to be black gue in one month and distances himself from the twelve year old girl so she doesn't have to see that. Cid gets his dreams crushed by Shera and for the following three years or so allows her to life in his house as long as he can verbally abuse her to his hearts content. it would really take him only a few minutes to find out that it wasn't her fault.

However far more important then all this Cid is funny and awesome while Cloud is angsty and awkward. Therefore, Cid is the better character and more of a hero.
