What I do believe is they have been taught by their instructors, parents, teachers and the Koran since childhood to hate and kill.....not to mention the physical and psychological abuse they do to each other and their children as they grow. Thus their personalities are prevented from developing as God intended....so too how their view of life overall is strictly and restricted through the lens of Islam.
Therefore the outcome we see consistently playing out in the East...and in any country where Muslims infiltrate...as one of abuse, crime, death and ultimately destruction....it can go no other way and almost impossible to change the mindset by any human means/p>
In the Quranic moral code, to kill an apostate or an infidel who refuses to submit is a GOOD thing. It is REQUIRED of them.
They would feel shame if they failed to kill.
