What is the impact of world war one on the characters in Compulsion and Mendel Bibliophile by Stefan Zweig?

It should be 3 main body paragraph and a good introduction and conclusion so in total 5 paragraphs, in each paragraph write about one of the impact of war in both stories and the same thing to the other paragraphs. Just focus on one point in each paragraph and explain that point in both stories.

Please remember to include a specific thesis statement. One more thing is to include the sources from the book and not from the secondary sources.
