Perversely, some governments reward terrorists’ (and other criminals’) families with monthly stipends[1].
Me of 20 years ago would probably be shocked at me nowadays, but I’ve slowly come around to thinking that only those who substantially share a moral framework with me deserve to be treated in that framework, and those who choose to act in a radically different moral framework probably deserve to be treated under that framework. In other words, I refuse to let my moral framework be used as a tool to harm me.
So I am not horrified by the discussion of family retribution and don’t automatically reject the idea without consideration.
