Fine I will explain it.
The question here is hope the greatest of all evil?
As hope is the final thing in the box, it is either
a) Hope is the final greatest evil of all
b) Hope is the greatest of good as it balances all the other evil in the box.
Hope lets people live, but living just for hope itself becomes a torment.
E.g : All anons hope to have a nice gf, but living with just hope alone and nothing else means all anons will never have a gf. So is hope prolonging the life of anons (evil) or letting the anons live in chance that they might indeed get a gf.
tl:dr Philosophical bullshits.
