How nice of you to cowardly snipe and run @aguleb, have you—as what I presume is a German—really chosen to turn your back on the atrocities committed by Israel because Germany once was the monster Israel now has become?
Nowhere in my reply did I "justify the killing of" any of those you mention. You, however, are completely disregarding the context in which Hamas (a group needed by, indeed financed by, Israel, by the way) exists; the context of more than half a century long occupation.
