Kant's Formalism states that it is an individual's duty to behave ethically, and rather have good intensions over results. In this case, you are letting the result of a possible bad relationship with your in-laws interfere with your good intensions. Therefore, this violates Kant's theory of having good intensions being more important than the outcome. In regards to Mill's Utilitarianism, the greatest amount of good would have been keeping the tender fair and not making exceptions for the benefit of personal relationships. This would keep the public tender fair but at the cost of possibly losing the best solution to the new water treatment system, and creating tension in your family. When you look at Aristotle's Virtue ethics which states that an act is good if it has reason. The primary act is to find the best way to implement a new water treatment system, and if you act in this way because you believe that you in-laws company has the best solution you are acting without reason as you are not aware of what other candidates have to offer. Thus, by Aristotle's Virtue theory this would be an unethical
