Obviously you're not interested in a serious discussion, however I'll entertain your other points about supporting Assad, which are again, immoral and illogical.
Syria is heading for Balkanisation, that is the best option for the people in that area, to be in their own states all ethnically/religiously homogeneous. Syria existing as a unified state will only lead to ineffectual government (See Lebanon or Iraq) or perpetual dictatorship, the latter which is now impossible due to the manpower shortages of the Assad regime.
If the US were to reverse its decision and support Assad, it would undoubtedly give the Jihadi movement another good recruiting sergeant for their cause, not to mention yet another moral blot on the public image of the US, not to mention huge rifts with the Saudis and Turks, two major allies of the opposition. As for ISIS, giving the Kurds actual tanks and artillery would produce more tangible results than just bombing campaigns.
Also Assads regime has killed more civilians than all the opposition groups combined, and the best he can do is a stalemate.
