I do not understand at this point after all that has gone on why characters would not drop their animosity(except towards Ben) and work towards a common goal. That goal being 'survival under the radar' given their situation. Seriously Jack/Sawyer Kate/Juliet and who ever else. Sayiad is in the ultimate "kill Hitler as a boy" scenario. Does killing Hitler now help the world better or worse in the future you came from? If you kill Hitler here does his pebble not dropping mean everything else unfolds as it should. Some also call this the 'Mephisto principal' but I digress. Next week should be interesting.
one theory about why not kill hitler is.. without hitler germany dosnt go to war against the soviet union. without that the soviet union dosnt go through all that and in the end we have a more dangerous stalin to deal with.
