I think it's relevant here.
Added to "don't understand" and "dont care" is a third option: "don't agree", based on different upbringings and cultural values, some of which you or I would find abhorrent, because of our own upbringing and cultural values. But I think you should recognize that there is a good chance you'd have the same beliefs if you had the same life experience.
What's the point of this line of thinking? Ok, maybe we'd also join the Taliban if we grew up in orphanages in Pakistan after Russia invaded Afghanistan. So?
The thrust of your arguments here (the article and the life experience thing) seems to be to not hold anyone morally accountable for anything.
Once you recognize that these people are human, you have a chance at maybe effecting some kind of change. Looking at them as animals means you will never effect any positive change, and you'll probably contribute to an even worse us-against-them kind of environment.
