Even Evil Has Loved Ones is a trope, much like Even Evil Has Standards, that is meant to show a villain is never completely wicked. Sometimes, this can appear as a villain having a parent, a lover, a child, or a friend they care about very much. Sometimes, if their love is strong enough, it will redeem the villain, but in other cases, their death may eliminate their belief in good and put them on the path of evil, in what is called the Despair Event Horizon. Note that this can only count if the villain is truly loving; in the case of a lover, if the villain simply has a crush that's not returned, it doesn't count.
