There is no such thing as "no intervention". Any action or inaction will shape events. In democracies it is inevitable to have an opinion of these things and to voice them. Otherwise leaders like Putin or Assad step all over you, and then demand "deescalation".
Also, Assad left any shred of legitimacy when he started decimating his population with artillery, and I don't how care how many "legitimate targets" where among the hundreds of thousands of civilians that were targeted.
For me, the only tolerance a democracy can have towards the governments in Syria, North Korea and some other countries, is that nobody can or wants to depose them. Nothing more, nothing less. That does not mean regime change works all the time, it just means there cannot be any apologetics for mass these murderers any more.
