The likelihood of being thrown to the sleen, is not an exclusionary factor, only a suggestive instance that it is easier perhaps for a slave to be tossed to the sleen, a hunter and tenacious tracker, rather than other slaves learning a lesson.
For the frees on the other hand, through the retribution factor of impalement used as a deterrence for crimes to be committed by frees, is worthy to be learned. Frees being more valued and looked at in a higher degree of worthiness than a mere slave, who is a simple beast of burden, at the beck and call of the frees in service. Thus the underlying philosophy of justice on Gor, is used at the empowering discretion of those in charge. Hence, honor, plays no role in impalement, just convenience.
