If I give money to a homeless person and they spend it on drugs, am I responsible for their choice? If I give money to a government and they spend it on weapons, am I responsible? Draftees, even in non-combat roles, often have to explain their service to future governments. Visas can be denied for many reasons, including that. My US visa conversion from J1 to F1 was denied because I was too poor, not having $40k in my own bank account at age 19, but the visa could've be been denied for many other reasons such as political differences: "communism", "terrorism".
