What are you talking, i can tell you there is a lot of desilusion in your saying.
You must understand that syria is 75% sunni muslim, and the shia alawi are no more than 10%. Even if they kill 100 000, they wont be able to stop the trend, sunni muslim are deserting the army en masse and integrating the FSA, you can lie to yourself as much as you want whats important is whats happening on the ground and the FSA is gaining ground every day.
And the more Iran show their eagerness to keep assad alive, the more the syrians will respond to this post assad.
In the end, better understand that assad regime is dead and start talking to the oppostion to try to save some influence in post assad, otherwise iran will be kicked out politically, economicaly, religously forever from syria
