Personally, I think one of the most disastrous defeats Rome experienced (in terms of historical consequences) was Adrianople. But, if asked who was Rome's most destructive enemy, I'd answer the Romans themselves. Throughout their history, civil wars wreaked the worst havoc on the their civilization. If Romans hadn't exercised such a proclivity for killing other Romans, we'd probably all be speaking Latin today.
