Another casualty of the military intervention was human rights. To be sure, Qaddafi was a cruel dictator, and his overthrow was a victory for those who care about human rights. But human rights law does not endorse the principle that the ends justify the means -- even if the ends are humanitarian. As Amnesty International reported, the rebel groups "abducted, arbitrarily detained, tortured and killed former members of the security forces, suspected Gaddafi loyalists, captured soldiers and foreign nationals wrongly suspected of being mercenaries fighting on behalf of Gaddafi forces."

That this would happen was surely obvious to the policymakers involved. That this would happen when NATO forces commit themselves to an air war, and refuse to send ground troops that might have imposed some discipline on the rebel forces, should have been even more obvious. But the fact is that a ground campaign was politically impossible. Thus, the choice was between non-intervention, which could have resulted in massacres and the prolongation of Qaddafi's regime, or intervention along with moral, if not necessarily legal, complicity in torture and crimes against humanity by the rebels. International law provides no guidance for making this tradeoff, and thus surely did not influence the decisions of the governments

This does make an interesting point I believe. Also this is the first I've heard about Gadaffi being raped, seems a bit far fetched.
