Conscripts viewed service as permanent captivity indistinguishable from slavery. [causal]
It is natural for any sane person to resist conscription, since conscription and captivity are [practically] the same. No conscript would ever have the hope of saying “I will be conscripted for a fixed period, then I will be discharged and live the remaining years of my life [outside the army].” Men have the right to think likewise since we do not discharge men unless they receive serious wounds in their hands, legs, eyes or heads; that is, they are not discharged unless they are good neither for the army nor [any other] service. This is why we face resistance in conscripting them.
Builds on: "Conscripts universally resisted through desertion and self-inflicted wounds."
