Well, i work on servers and we used to get replacement cpus that had bent pins sometimes and you really don't have to get them completely straight to work. Most of the time the pin is in one of the outside rows and if you carefully put that side in first, it will go in...... I have had some luck in bending pins back, but some of them have broken when doing it....seems like when it is not bent all the way down, it is fine. The ones i've seen that were bent all the way down... not so much....
Now, most of the time they are intel, so no more pins on the cpus..... but sometimes we get a bent pin (not sure you can really call it a pin) on the cpu socket on the motherboard and then, eh... sometimes u can make it work...
