Terrorists keep blowing themselves and others up, but they never get what they want. Will they ever learn?

According to my careful prognosis they are PISSED off because they don't want a thing.  They are haters and they hate the fact that anyone can experience joy when they don't even know what it is.   Some have suffered so abominably, it is understandable.  Some have not suffered at all, but are just in that hate atmosphere.   Kind of like being raised by White Supremacists.   So, they want to spread their anger and PAIN around because that is their only recreational outlet left.
