You really don't have anything to lose, because you can't use it the way it is now. Just be extremely careful. There are a number of guides online, even some fairly reputable ones, regarding making pin repairs to Intel LGA style pin assemblies as well as to AMD style on the CPU pins. Obviously, those are a bit easier in most cases than the ones on the motherboard, but don't be surprised if that pin bent completely 180 degrees from where it was originally, breaks while bending it back.
Whatever you do, don't bend it back ANY further than you need to in order for it to be where it needs to be and make contact with the contact points on the bottom of the CPU. Bending it further than necessary is the one sure way to make certain that the metal breaks off from fatigue, and with that kind of metal "fatigue" doesn't take all that much to happen.
