Empathy is the ability to emulate the contents of another consciousness.
While an agent could mimic empathetic behaviors (and words), given enough interrogation and testing you would encounter an out-of-training case that it would fail.

This is also the case with regular humans.
But also, how do you know that LMs aren't empathic? By your own admission they do "mimic empathetic behaviors", but you reject this as the real thing because you claim that with enough testing you would encounter a failure. This raises all kinds of "no true Scotsman" flags, not to mention that empathy failure is not exactly uncommon among humans. So how exactly do you actually test your hypothesis?
