And they are going to care about claims regarding ultimate truth in the universe that dont derive from Islam, why, exactly?Those looting artifacts aren't going to listen to your carefully constructed philosophical/ethical arguments.
Problem. Contrary to what Starglider might think on the subject, it is not logically consistent to favor one's own family in a Utilitarian calculation, let alone another sapient species or civilization. The only reason there are ever logically consistent differences between entities in a utilitarian calculation is a difference in experiential capacity. Likely based on thresholds for various stimuli and actions rather than a continuous scale that covers everything.If Utilitarianism is about maximizing well-being, there is nothing wrong with that beyond the problem of its application, hence my point about slavery being acceptable under utilitarianism, because, like any philosophical system it can be applied in multiple ways. It may not be how those who invented it intended, but it would be perfectly acceptable for me to say: "Ok, I am a utilitarian, I find that to maximize the well-being of my group I will use this here Death Star to annihilate a planet of some other group and thus prevent a galaxy wide civil war and untold carnage."
(for example, rather than saying a rat is worth 1/10th of a person for all calculations, is more accurate to say that rats experience physical pain the exact same way we do, can experience immediate stress the same way or close, but cannot experience existential angst at all).
The degree to which weight is placed on different entities has to be grounded in this little thing called "reality".
One must also take the Best path, not just the path that is less bad than the worst one. Avoiding war without destruction is the best option, unless war is inevitable (it only takes one party to start one, and there are instances where war is the preferable alternative. Take WWII for example. Had it not been fought, Hitler would have committed genocide against all of Russia). In which case, geocide is likely not the best option for conducting that war.
Normative ethical systems are derived not from some sort of cosmic truths, but through the logically consistent application of our common moral experience. They are a attempts (that succeed to varying degrees) to strip away all the biases and other cultural BS, and create an objective means by which we can direct our behavior based on things every human (at least) can understand. In that sense, they are Universal, but not Absolute. Specific actions are not proscribed or prescribed. Principles get applied to solve problems, and the actions taken derive from those principles based on the circumstances of the problem.
