Individually there are counter examples, but does any other species display empathy at the scale of another species? I doubt it. And the species that do display empathy at an individual level will also display cruelty.
Humpback whales appear to show empathy towards other species. We have 115 documented cases of them doing so (and it is a lot given how hard it is to observe them).
How do you distinguish between individual acts of empathy and "empathy at the scale of another species?"

Sounds like that applies equally to humans. There are cultures where cruelty towards dogs and cats is more common that empathy, and even in places where empathy is more common, individuals can still be cruel.
A "Save the Whales" campaign may seem like empathy towards another species, but it only exists because humans hunted whales so vigorously, and are also in the midsts of ruining their environments, so neither of those sound like examples of true empathy towards another species.

An invasive species (or if an imbalance occurs such as predators become scarce and prey population explodes) will just outcompete other species for resources with no empathy. Humans can certainly do that, but we also sometimes worry about preserving species and habitats.
Since we've caused more species to go extinct than any other invasive species in history, that's a remarkably ineffectual case of empathy.
In any case, I'd argue that this isn't real "empathy." We feel intellectually that we've done something wrong, and we even feel sadness about it (although possibly in a similar way that we'd feel towards abiotic ruin, like destroying all the arches in arches national park), but I don't think we truly empathize with the, say, beetles who are going extinct, as we cannot comprehend their minds in any way.
Since this whole discussion is about theory of mind, we should use empathy correctly: "the ability to understand and share the feelings of another."
How many other species can afford the time to express empathy as much as humans do? Most of them are just struggling to survive, so it's not like we get a lot of opportunities to observe that behavior.
So two examples come to mind where it wasn't just survival. One, a wolf pack in Yellowstone invades another wolf pack's territory, chases them away from their dens, forcing their cubs to starve to death. And two, the brutal Chimpanzee war Jane Goodall observed between two tribes. A third example could be any ant conflict between two colonies where they could in theory both survive but instead choose to try and wipe each other out. In fact, some ants form super colonies instead of fighting one another.
