In a word, YES it can bork your CPU if the pads on the cpu make the wrong contact.
Whether or not you bend the pin-s back or not has to be a judgement call on your part...I would say it needs to be done, but if you don't have the confidence to do it yourself, you can RMA it if it is still under warranty.
No I would NOT power it on with a bent pin So be very careful if you decide to fix it yourself...if you can try to find some "hemostats" with the pointed end...very handy in electronic and delicate computer work and use them to straighten the pins...you may have to go just past center when bending them back in order for them to line back up naturally
Hope this helps,
