Hypotheticals on Ethics and Punishment

Caution: I come from an engineering background not a law background

Punishment has potential to be seen as useful. Punishment done wrong has potential to be problematic in many ways.

Would it be immoral to put someone in stocks naked in a town square for a month?

What are the moral implications?
What crime did they commit?
Why do it?
Can a punishment, be involved in a specific punishment be unseemly, reduce the character of both the victim and the deliverer?

Does the punisher have sufficient grounds to make sufficient judgments?
Were they commissioned by others, laws and regulations that were put in previously and to serve who?

What are the Human Rights implications?
Is there any potential for slippery slope saying one thing is ok, to saying another thing is ok?

If you wouldn’t do it to a friend, or a family member is it ethical to do to another?

Will it make society better?
Will it foster positive change?
Will the cost be too expensive for self or future generations?

If someone was pushed to promote such a punishment or give such a punishment what would be the causes?
How could one prevent the causes in the first place?

Decision making is made based upon rational approaches at times, is the way of thought logical?
Even if the reasoning is logical, is it made based upon ideal comprehension, will ideal comprehension ever be ideally invest in?
If ideal comprehension is not invested in is it ethical to give such a punishment, is it wise to think giving such a punishment will have no implications?

Could a person that is punished for a month in a horrible way become powerful later?
If that person becomes powerful later would the punishment have any lasting effects visible or not visible in a way that could be harmful to society?
If a punishment has potential to harm society in the future is it just?
If a punishment robs someone in the future of justice or has potential to do so, is it just to issue in the first place?

If the punishment has potential to be seen as harmful at some future date will that put leaders’ character in a less-than-ideal position?
Is it useful to others to have other leader’s character in a less-than-ideal position?

To be clear I think the punishment is wrong due to Human Rights implications yet I am unsure of the crime that might see it as useful.
