Bite and Devour

For the whole law is fulfilled in one word: "You shall love your neighbor as yourself." But if you bite and devour one another, watch out that you are not consumed by one another. -Gal 5:14-15

Why do we need to warned about being consumed by one another in the context of controversy, but not in the context of love? Why does Paul simply tell us to love each other--with no qualifiers about taking it too far? But when it comes to arguing, he immediately tells us to be careful not to be consumed by it? I can think of two reasons:

1. Love doesn't threaten to consume us because it is contrary to our selfish nature. Whereas arguing and divisiveness is so natural too us that it easily will consume us if we aren't careful.
2. We can't take our loving too far. If we were somehow consumed by love, that would be a good thing, so there is no need to be warned against it.
