Levi's Shame

Primo Levi writes very compellingly. I have found his writing incredibly captivating. Levi mentions several forms of shame within this chapter. For my blog post, I wanted to discuss the forms that he mentions within his piece.There is the shame or guilt of being alive in place of another. There is the shame of the world. There are other forms of shame, but I found that shame of the world is something I would like to focus on.
Levi refers to shame of the world as "no man is an island". I found the definition of what shame of the world could be to be a bit confusing. He uses the example of how the German people 'delud[ed] themselves that not seeing was a way of not knowing, and that not knowing relieved them of their share of complicity.' So is world shame something that is a collective shame felt by say a nation's citizens? Or is it something else?
