Supplying weapons is neither proof that these people are thugs, nor is it proof that the rebellion was not genuine.
Then you probably should educate yourself on his regime and its policy towards Libyans, both at home and abroad. The US's support of Libya is something along the lines of their support for Pakistan -- the enemy of my enemy is my friend. Gaddafi was not a popular figure in Western circles.
I have no "perception of behavior." My opinion on the rebellion is that it was genuine. Once NATO saw that momentum of the Arab Spring could potentially carry this rebellion all the way to Tripoli, they pounced on the opportunity to back the rebels. Gaddafi has been an unpopular figure in the West, mostly for his ties to terrorism, but also because of his brutal regime. NATO took the rebellion as an opportunity to displace him and install another democratic government. Whether that last bit comes to fruition remains to be seen.
Your failure here is to provide one iota of evidence that these men are "thugs." You cannot even define what you mean by the word, though you can tell me specifically what it doesn't mean. I don't see any evidence that the men who started this rebellion were hired by NATO and you have yet to provide this information.
