did none of you take an intro or social psych course, ever?
humans will transform into lemmings in a heart-beat.
i'm sorry for that boy. dreadfully sorry, but what those folks did was to be expected, and i guarantee you each would have done the same. we don't know how big or fast that man was or if he had ever been trained in special forces and snapped because of post traumatic stress. i don't think he chose his victim b4 hand. i think he snapped and that poor kid just happened to be there. it could've been anyone. who carries around a butcher knife? why not kill the boy earlier? why wait til he's on the bus? surely if the killer were "sane" he'd have tried to do the killing in a less conspicuous manner to avoid being caught. the killing was random, and a result of the killer's emotion/mental state. from a non psychological perspective, the other passengers had no way of communicating instantly with one another to stop the man. the poor kid, depending upon the 1st couple of wounds, the victim may have already been dead way before the end of the killer's onslaught, which means there would have been absolutely nothing they could have done to begin with. this type of judgment could only come from the uneducated. we should be sad at the event, but we should rejoice no one else had their lives' taken.
