Don't reuse it. I've reused it once when I was waiting on a new one to ship, but as soon as it got there swapped it out. Reusing an axle nut fits into the high-risk, low-reward quadrant that's best to stay out of.

Don't want to start an argument here, but I have to pretty strongly disagree. There is virtually no risk to reusing the axle nut. The chance of it backing off is, and I'm not exaggerating, zero. So long as some part of it is peened back over that is, or if it is torqued back down good. Optimally both should be true and you"ve got double redundancy. Like I said, I've reused a ton of axle nuts with no issue. Probably multiple dozens at this point on various makes if vehicle.
