Animals understanding of “morality” is extremely different to what we as humans understand as moral, and I’d argue that you can’t actually ask them what they think is right or wrong, so you can’t really know if their behaviour is based on morality or… well, anything else.

Regardless, semantics aside my primary question was how you arrive at the position that “gaining from someone else’s loss is wrong” is an objective position to take… because I think that is just something you think is wrong.
