Perhaps animals display empathy, perhaps not, regardless they certainly don't display ethics, morality, or fair play.
Besides, your assertion that those things are based on empathy has no support that I've ever seen. On what do you base your opinion?
Well, some social creatures(dogs for instance) will protect eachother from enemies. Sometimes they will give food to eachother. Sometimes they are visibly sad when a fellow packmate is injured or killed. These are examples of rudimentary empathy, aren’t they?
