How tragic. It is so human to try to make sense of a life filled with so much suffering by blaming that suffering on one's own actions, or even on the actions of others, when the actual cause is likely uncontrollable. Especially when there was such a small amount medical knowledge in the early 1900s to be able to know what that cause is, for certain. It even happens today with a huge amount of people, with many known and unknown diseases.
