Is the war in Libya really justified?

For months now NATO and many supporting countries around the world have been supporting rebel forces in Libya. No matter what your stance may be on the issue, one fact is clear, many innocent civilians have been killed in the relentless fire fights, shellings, & bombing campaigns. Do you think this support mission is truly justified? Is this no different than most western countries foreign policy goals of the middle east region? Libya has a lot of oil, just remember that.
