Saddam and Gaddafi were as bad as Asad is now , but you obviously will hate saddam only because he generally oppressed shias.
Syrian revolution was started by syrians, like the bahrainis. But bahraini dictators aren't half as bad as Assad in his repression. Torture, genocide, rape , extermination, burning people alive, barrel bombs, chemical weapons -- the list goes on and on. Bahraini clown hasn't done a fraction of this but doesn't matter, he is against shia iran ... Labbayik !
And by the way, a 'game' is played by two sides. I don't know what makes you think Iran/Assad/Putin/shias are lesser evils apart from they represent the political interests of your sect in the middle east.
