Answer:
Both Niemöller and Ogden are criticizing the silent bystander that allows injustice to happen only until it affects him and then realizes that there´s no one there to stand up for him.
Step-by-step explanation:
Ogden´s poem tells the story of a town that allows a mysterious hangman to kill people in the name of justice without much explanation. By the end of the poem, the hangman explains that all he did was what people allowed him to do. In the same way, Niemöller´s words are those of someone who realized too late that his silence was a form of complicity.
