What idea does kollwitz say motivated her son and other young Germans to rush to war?

Käthe Kollwitz suggested that her son and other young Germans were motivated to rush to war by a sense of idealism and a desire for heroism. They were influenced by societal notions of duty and nationalism, which glorified the idea of fighting for one's country. This fervent belief in sacrifice and the pursuit of a noble cause overshadowed the grim realities of war, leading many to enlist with a sense of purpose and conviction. Ultimately, this idealism tragically contrasted with the harsh experiences they faced on the battlefield.
