No need to take it off line, you've made my point nicely. You are correct to the extent you are interpreting the reasons we have ethics, but you are missing the deeper ethical issues that develop when two rules that are both "correct" and "moral" are in conflict.I would say the same. You are entitled to your opinion as I am mine.
It is wrong to tell someone to break a rule - period. The rules are in place for safety.
The operating pressure is physically stamped on the tank. That is the limit of the pressure for general use.
Breaking the rules, breaking standards, breaking the law is unethical.
Ethics is a guideline to help us navigate a situation that has no rules to guide us. Ethic's is a guide to help us navigate a rule that is wrong, unsafe, morally questionable, or the rule itself is illegal or imoral. Ethics allows us to stand up for what is right even when told to do something wrong.
Tank pressure, stamped on the side of a tank, it is NOT an ethical discussion.
If you'd like to take this 'off-line', feel free to do so. Publicly berating someone is also questionable.
For example: When working with a client do I choose to weigh the decisions made in favor of letting a person excercise Autonomy even if it creates some risk for them, or do I weight the decision in favor of Nonmaleficence or Beneficence to prevent harm. Recognizing the value of letting the person try and possibly fail is essential. It often comes down to a cost / benefit or best case / worst case analysis and may hinge on whether there is risk of permanent harm. Physicians do something very similar with many treatment decisions where there are both risks and benefits.
It also means that one decision may be right for one person and an opposite decison may be equally right for someone else. Rules cannot create that degree of precision in making the "right" decision.
In comparison, cave diving and overfilling tanks is an easy one as the benefits clearly outweigh the theoretical risks, which so far are zero based on the zero accidents that have actually occurred.
