It’s all so simple. Someone or some group takes a person hostage and says “give us what we want or we’ll kill the hostage.” The choices are 1. give them what they want or 2. rescue the hostage or at least kill all the hostage takers so they’ll never do it again. Number 1 encourages such behavior. Number 2 will discourage such behavior at the same time that it eliminates the smaller number that refuse to be discouraged. Number 1 is the submission of one’s will to that of the malefactors and saying that they are part of the same society and, because one gives in to them, the more important part of that society. Number 2 is the declaration that the malefactors stand in relation to human society in the same way that small pox stands in relation to the human body—they are an alien species that is up to no good. They may have their own desires and goals just like we do but what is good for them is not good for us and we don’t have to pretend otherwise or feel bad when their predation is crushed.
Deserves repeating. Again and again.
