Russian school hostage crisis

I and the public know.
What all schoolchildren learn.
Those to whom evil is done.
Do evil in return.
-W.H. Auden, poet (1907-1973)

No matter what their cause is, those who hide behind
children to save there lives, those who kill children
are not human beings.
Show no mercy towards them.

If you have a cause and you want to fight for it then
it should be man to man, face to face.

Is this what Kuran teaches Muslisms?
Do these people have faith in any religion?
I doubt....
