Note that the Greek word agape means more than just Godly or principled love. It is also romantic love. Even the lust Amnon felt for his half-sister Tamar is translated as agape in the Greek NWT.

2 Sam 13:1, 4, 15:

1  "...and Amnon the son of David
fell in love
(αγάπη) with [Tamar]...
4  ...At this Amnon said to him: "With
Tamar the sister of Absalom my brother I am in love
(αγάπη)."

And after he had violated her:

15  "And Amnon began hating her with a very great hatred, because the hatred with which he hated her was greater than the love (αγάπη) with which he had loved (αγάπη) her..."

In Hastings. J Dictionary of the Bible, under the reference for Love in the LXX we read:
All these varieties of love, human and divine, may in the LXX be expressed by the verb agapao and noun 'agape'. In the story of Samson and Delilah agapao describes sexual relationship (Judges 16 v 4, 15) not to mention Solomon's legalised lust (3 K 11 v 2), besides expressing love in its higher reaches…. In the Greek Bible in the form that it must have been known to the NT writers, agapao does duty for every shade and variety of love, for divine pity and preference for Israel right down to erotic passion. It is true that agapao is not the only verb to express erotic love in the LXX, for there are also pro-aireomai and enthumeomai (Heb hshk ethelo hps); but it is very commonly used to render Hebrew hb when the context makes plain that this very type of love or passion is intended. Nor has agapao the monopoly for rendering what may be described as reasoning attachment; thus the more usual verbs for divine pity are eleeo and oikterio. The noun 'agape' is usually connected with sex, or at least with the love of women; or it is a passion comparable in intensity with hatred; it is not at all a higher love than philia. Indeed in the LXX agapesis may be said to be a higher type of love than AGAPE (c.f. especially Hosea 11 v 4, Zephaniah 3 v 17, Jeremiah 38 (31) v 3)
