Wolves of Norway are nearly extinct, leaving humans with the responsibility of controlling the moose population. Albinism almost always comes with moderate to severe vision impairment. So any argument about it being beneficial is almost certainly incorrect. Because albinism often produces photosensitivity, the moose would be almost totally blind and in pain in an environment as bright as Norway's arctic long days and bright white snow.
So given the highly genetic nature of the albinism trait, it would probably be best for the population if this particular moose were at least sterilized.
And no, we don't kill people with albinism. But if you can develop a personal relationship with a moose and convince it to wear corrective lenses and submit to sterilization, make sure and let us know.
