No it really isn’t hard to comprehend....when you hear a three year old toddler spewing hatred...and you see them treat their own families and fellow Muslims this way...when their minds are filled with death....then this action is easy to understand why.
Something else too, these hatcheting jobs and decapitations are seen by children as a norm, they are not sheltered from this...so they have seen these types of brutal events from childhood to adult...they are unaffected by their own behavior..it’s known and understood as the norm.
Just like abortion is for much of our culture. Abortion is the treacherous, blood spilling practice of murdering the most helpless, innocent and beautiful among us. Often ripping them apart limb by limb until their skulls are crushed and they are removed to be thrown into the garbage like filthy refuse. It is our culture's rite of blood sacrifice to Satan. Many do not give the practice any mind but many others champion it. How different are we than they?
Luk 6:41 And why beholdest thou the mote that is in thy brother's eye, but perceivest not the beam that is in thine own eye?
