What central argument does Wiesel present in this speech? Explain citing details from the text

In his speech "The Perils of Indifference", he wants us to know that when someone is indifferent to the suffering of another he/she is just as guilty as the person causing the suffering. When we stand idly by and do nothing we become accomplices to a crime against other human beings. Wiesel's speech emphasizes that this is how evil takes hold. We are all in this together, and we must stand up to evil wherever it exists.
