Aztec Sacrifice and Prison Labor

Aztecs used their prisoners to sacrifice to their god.They took advantage of their prisoners I believe we should too but not by sacrificing.Prisoners live in prison and they don't pay for anything I think they do get punished for what they do but some what they get rewarded for not doing anything.So the should help the government by doing some helpful jobs.They can do some jobs without getting paid.It might help others freely and help the prisoners out.I believe that it won't hurt anyone but help others.
