Need help with my thesis on the Aeneid

I've been stuck on trying to write a good thesis for my literature class on Virgil's Aeneid.

So far I have the following:

'Dido's death and the fall of Carthage, demonstrates the destructive force and consequences behind love.'

Is this still to broad of a thesis, and if so, any ideas on how to narrow it down?

Thanks for you time. :)

How?

If you can come up with a good answer to that question, your thesis might begin to seem a bit more focused.
