I think it’s safe to assume any highly evolved alien species will have moral constructs that support self-preservation.

Whether those morals extend to preserving other intelligent life forms (I.e. humans) seems unlikely since the prosperity of other life forms will inevitably lead to more competition for scarce resources.

The fact that human moral constructs apply to other intelligent species seems to be a bug that arises solely from the fact that we’re currently capable of out competing all other intelligent species.
