The doctor hoped to make the world a better place.Even if you can change the world, you can't change the society. That is just human nature.However, he could sense his own limitation.The law remains unchanged, the survivors of the concentration camps are freed, only to be re-arrested again after the war...Even though he abandoned his own country... and won the war, the world did not become better, not even a little bit."Wisdom and Effort"
Manchester city's mottoYou can replace a man, but you can't change society, is it?
