Mmigration question ?

ok let me rephrase my question, do you believe that if an immigrant breaks a law, pays the price set forth by a sitting judge, rehabiltates themselves, and move on to become respected members of society, and build families of law abiding citizens that they deserve to be torn away from their families decades after they paid their price to society? (and i dont mean violent crimes, lets say they commit a crime of theft of say $200) do you think deportation is a fair punishment?
