You don't really believe that the state defense the weak, do you? Well, there is social security and such, but it isn't like the state is very interested in defending the average citizen.
You know very well, that if you kill a burglar who is about to rape your wife or daughter in their own bedroom 2 o'clock in the morning, you risk jail. How could this even be possible, if the state wants justice? How can you not have a carte blanche to kill someone who is attacking your family in your own home? It barely even exists in America nowadays.
Since people are stupid, you need to shock them like Pasolini did.
