I have a burden on my soul. During all my long life, I did not make anyone happy, neither my friends, nor my family, nor even myself. I have done many evil things. […] I was the cause of the beginning of three big wars. About 800,000 people were killed because of me on the battlefields, and their mothers, brothers, and widows cried for them. And now this stands between me and god.

~ Otto von Bismarck
