Since non-JWs are 'dead meat' in their eyes , or only of any use if they can 'save' them and in so doing 'save' themselves I wouldn't expect JWs to, as an organization, really physically help anyone. Many a time have I heard the 'angel of Calcutta' derided for helping people, physically.
I'm certain that there are individual JWs who would move heaven and earth to help their neighbours but would make sure no one in the Cong new about it, in case of reprimand.
The Society, unfortunately, is cruel and heartless to the people of 'the world' of which they believe 'we are no part.'
Many a times was I ashamed to see religious leaders and ordinary people being depicted as being destroyed in terrible ways at Armageddon. They are probably holding a 'told you so' lofty attitude about the Tsunami as we speak. Why would they want to help when they can have that kind of view.
