Any harm the Beasts caused to humanity are passing influences, they don't destroy humanity for the sake of it. Goetia destroyed humanity to use the energy as fuel to change the foundation of life, removing the concept of death for humanity. That is his love and pity for humanity. Tiamat is the earth mother goddess, she has a very instinctive and primal love for humanity eventhough she hates them for abandoning her. That is a sort of love which cannot be comprehended by humanity. Kiara also loves humanity and wants salvation for all life, but due to her past experiences and how she grown up, her perception of humanity was twisted.
Sure there is a Beast candidate who tried to destroy humanity but for the sake of her love for a wizard on the moon, which is why Gil called her a "new" one. But the concept is always hate together with love.
