It's not about understanding, it's about alignment of drives/intentions. Humans who are arseholes have drives and understandings that are vey human and reasonably understandable, but they're arseholes nonetheless simply because these drives are in a bit of a conflict with what others around them would like to and they don't care much about the desires of others - just like most cats.
