Final answer:
Kantorek is the one who encouraged the boys to enlist, filling them with patriotic ideas and portraying military service as a path to glory.
Step-by-step explanation:
Based on the context provided from the various literature excerpts, although the question seems to relate to an unidentified literary work, it strongly resembles the theme and scenario found in Erich Maria Remarque's novel All Quiet on the Western Front. In this novel, it is Kantorek who is primarily responsible for encouraging the young boys to enlist for military service, filling them with ideas of patriotism and heroism.
Drawing from the excepts given and the resemblance to typical scenarios where authority figures such as schoolteachers, religious leaders, or military officers urge young men to enlist, Kantorek, who is like a teacher or a mentor figure, fits the profile of someone who would encourage enlistment based on patriotic fervor and promises of glory.
