What is the difference between deontological and teleological ethical systems for the control of ethical practices in criminal justice?

Deontological
ethics are concerned with absolute rules about what actions are acceptable, regardless of the
consequences of an action or the specific context.

Teleological ethics are
concerned with the result of actions, rather than absolute rules.

For
example, it's a deotological perspective to say that attempted murder is wrong, even if no harm
is caused. The choice is what matters, not the results. A strictly teleological perspective
would view accidentally causing someone's death as worse than trying but failing to kill
someone.

In thinking about criminal justice, a core question is whether a
system is ultimately about punishment or about results. A deontological perspective might argue
that it is proper to punish those who break the law and ignore the results of these
punishments.

On the other hand, a teleological perspective might note that
incarceration has generally been shown to only produce more violence and argue for the abolition
of prisons.
