your cpu and system are just fine...if one is careful enough its safe to unbend a pin...just ensure that its the same distance from all other pins etc...which you did.
It's just a contact point like any other and we all know that gold is very ductile so your pin is not damaged(develops cracks, fatigue loading) by unbending.
The voltage and current per pin is small that it cannot short, or heat up the pin either (Unless you over tighten a heatsink and bend the mobo or you OC in a dangerous fashion).
I am in India and know a few vendors who straighten out bent pins occasionally rather than RMA'ing the board and I have not seen a single failure yet..maybe luck or may be we get paranoid a wee bit too much...GOD knows
You are safe...enjoy using your system
