A change in government is never a bad thing. When the people of a country feel oppressed they should have a right to rebel their leaders. I.E. USA, French Revolution. etc etc.. This change brings new leaders into power which could change the country's economic and public relations with many other countries.
Unfortunately, the Syrian Rebels aren't saints fighting for a better cause. It has been proven that the Rebels use some of the same brutal tactics as the very enemy they fight daily. Both sides continue to commit atrocities on the people of Syria, and a better solution than civil war needs to be figured out soometime soon.
