I am totaly agree with you , the evil should excuse evil , btw it's law in Islam.
look , for my opinion ,we are here study the consequences of the wars of the west against Muslims .
this is a video very simple exemple of the causes of the terrors and make more hate to the west .
I remeber when some one post it in the facebook , all the people start insulting the west on general (not only the soldiers) .

For the religion , Islam never teach to torture or kill or abuse , if some muslims misuderstand the Islam or did not respect it (break the rules of Islam) it's called
extremity .
for my opinion ,there are two kinds of extremity : one is made by the hate to the west, because of the crimes .
the second misunderstand or don't respect the
Islam law .
