If I were to set about tidying a house by messing up the parts that were tidiest you'd think I'd gone nuts, yet this is precisely what the terrorist does. Instead of finding ways to bring comfort and order to places people are suffering using their God-given ability to love, be logical and speak up, they make more negative chaos, more mess. All they do is make things worse for everyone. They aren't simply bad, they're dumb.
The logic of the terrorist is broken. When you make people afraid their empathy centre shuts down, they become less logical, more primitive and harsh. Thus the terrorist is a huge part of the problem. They think they're speaking up for their cause when in reality they shoot both friend and foe in the foot.
To make a better world we need to make the functional stable parts more functional and stable, only then can we expand that stability around the globe with new technology to lift everyone into a better way of living - as such the terrorist, no matter the mantra, is everyone's enemy, rich and poor.
Our most highly evolved features are our empathy, our logic and our self control. When use these functions we can bring peace, grow trust, and honour our creator, showing that we are a good species capable of sustainability. The terrorist, the conspiracy theorist... they all lack essential parts of these higher functions. Thus we can choose to follow those who have achieved good mental faculties, or the pied pipers of paranoia.
