That would be an incredibly bad argument. Because it's not a motive, it's just descriptive. "we're at the top so we have the right" it's just a claim we make for ourself without considering how we got there.. and what if a smarter, more advanced alien race would come down to earth and conquer us?

And love.. we also feel pain.". So these are important to us.
