This applies to more than just terrorist. We should practice restraint in our everyday lives. We have the right to free speech. Does that mean we should bad mouth the government 24/7? Don't get me wrong, you can share your views but surely you can find more than one topic to speak about. We have the right to pursue happiness but should it come at the expense of others? Just because you are having a bad day doesn't mean you should ruin everyone else's day. When you make others pay for something that they had nothing to do with, you are no different that these Chechen terrorist. They are unhappy with the affairs of their country so they will get revenge by blowing up innocent Americans. The common thinking of the day is take advantage of everything you can, but does that mean you have to? You can lie on your resume to make yourself a little more impressive. Does that mean you should? You can lie about your marital status to get more welfare assistance. Should you do that, just because it's easy? If no one is watching the back door at the appliance store, must you grab a flat-screen and run? Just because you have the ability to write a hateful letter to someone should you actually send it to them? You can easily lead a double life without your wife and kids knowing about it. That doesn't mean you should. Again, a society without restraint is a society that will readily destroy itself.
Without some moral code we are nothing more than vicious animals. If we don't have a moral compass we will surely get lost in ourselves and do irrevocable harm to others. Just because there is an opportunity doesn't necessarily mean you have to take it. In the end if you are not true to yourself, no one will be true to you. When you meet your Maker, the conversation will be on your choices not your abilities.
