Right now, as we speak, attack bombers of the Syrian air force are massacring civilians all over Syria. Just over the hill, on the other side of the Golan Heights, is a powerful and sophisticated air force that could blow the Syrian air force out of the air in hours - the IAF, the Israel Air Force. One can imagine that in return for a guarantee of a peace treaty and normalization of relations, that Israel would be glad to help the FSA, the Free Syrian Army, unseat Assad.
The fact that no such thing has happened nor will happen, in and of itself shows who the Free Syrian Army are and what they are fighting for. The fact that the regime they are fighting is despicable does not make them the good guys by any stretch of the imagination.
Most of what we have read about the FSA is that they are fighting the Assad regime for two reasons - that it is secular and that it is run by Alawite Shi'ites, not Sunnis. Neither reason has anything to do with the freedom and democracy they tell Western media they are fighting for.
