No the NATO should cooperate with countries like Saudi Arabia, Turkey, Egypt and Jordan to take out Assad and ISIS as well and bring peace and stability to the region. That is the only solution. Death is death no matter what means is to be used. Assad has been killing his own people for almost 4 years but he is not using the method ISIS is using yet the word is turning a blind eye to that forgetting that it was Assad, Hizbollah, Iraq and Iran who facilitated the existence of ISIS in both Syria and Iraq in order to prolong the conflict. The US on other hand isn't innocent as it contributed to arming of ISIS either deliberately or mistakenly.
