We know that after the second war, Dementors were removed from Azkaban by Kingsley. So I am assuming Azkaban would be guarded by some Aurors.
Will it be possible for a captured Death Eater to escape from Azkaban now?
How is it that many Death Eaters still remained sane after spending many years in Azkaban? I am talking about Bellatrix and others who were captured after the first war.
