It can kill a component faster. I've never had a CPU die on me though and have been overclocking for ~10 years. If you run can Prime95 or OCCT for 24 hours(i only did my burn in test for 6) with out crashing you should have a stable overclock.

When amd or intel tests there cpu chips there a set tests that if a chip passes it gets binned as x speed. if it fails that set tests but passes at a slower speed it gets binned at the slower speed. cpu and gpu vendor dont toss out chips on wafers that not pass at the max speed. they get re binned as slower parts. when someone over clocks there cpu or gpu they seeing how good the chip waffer is and how far they can push the chip and it still be stable. with over clock there are some chips that are just bad and wont...rig will lock up....other with good air cooler can hit good over clock and be stable.
most time if your doing the over clock right then under burn in time the rig will lock up...have to lower the voltage or the clock speed. if yu put to much voltage on a part you burn it out. also pushing the chip close to it breaking point can shorten it life. the good over clockers dont look to push there cpu/gpu to the breaking point. they looking for slighly more speed without burning anything out.

If done properly there should be no damage to the CPU. Other than better performance, the other thing you get is more heat. If the CPU is cooled properly to keep the temps to a reasonable level, then it should be fine. OC'ing also involves increasing the the CPU voltage though. The higher the OC the more likely you need to increase the voltage.
Too much voltage can damage a CPU regardless of how cool the CPU is kept. There is no way of know how high the voltage settings were increased to (if they were even increased).
In most cases I would say people replace OC'ed CPUs not because they failed, but because the OC'ed CPU no longer provides the performance they want to they simply build a new PC or install a more recent generation / more powerful CPU.

1. A CPU executes instructions given to it per cycle (like 1Ghz is 1 Billion cycles/Hertz), overclocking raises the number of cycles so that computer instructions are executed at a faster rate hence better performance.
2. It's hard to kill a CPU by overclocking, today chips have fail safe methods that protect itself from dying. If the chip gets to hot, it shuts off, if it can't run on high voltages it'll BSOD or shutdown.
3.It might, sometimes chips can't handle the extra voltage, heat or sometimes your particular chip just doesn't like to have it's clock raised. Again generally, if something goes wrong your system will tend to display the abnormalities i mentioned above (BSOD, shutdown etc).
4. Overclocking does put more wear on your system because it outputs more heat and heat deteriorates computer equipment. Granted as long as you have a cooler that can dissipate that extra heat, it's really a non issue. It's not like you're going to be shorting your computers lifespan by five years from just a tiny overclock,
