I'm not sure I understand what you're saying, are you assimilating Sarko's intent with that of an armed mugger's? If so, I wholeheartedly agree, but I honestly don't think Bush was really trying to save anyone's life when he launched the war on Iraq.*
Seriously, the humanitarian excuse has been resting in pieces since it was made the coalition's official position that Qaddafi has to go; the fact that allied air forces are basically paving the way for the rebels' advance in clear violation of the provisions of resolution 1973 doesn't help either.
*He probably did, what with Saddam being the accomplished stalinist he was, but I think of that as accessory.
On the contrary, the humanitarian intent of the UN resolution is nonsense WITHOUT regime change. That's my own analysis and those of articles I've been reading but I must apologise since I didn't bookmark them. By which I am talking in terms of common sense rather than legal prestidigitation - which I have solid and unshakeable contempt for.
