Would you volunteer to die for the greater good (see details)?

If you somehow found out that your death, regardless of how it came about or when would bring about world peace, would you volunteer to die sooner than you otherwise would? And by this I mean, whether you shot yourself in the head right now, or just lived the rest of your natural life, even if it takes another 90 years before you die, your death would bring about world peace, a lasting world peace without end, what path would you choose? And I mean, there is no doubt in your mind, you know this to be a fact, you have 100% complete faith that this is true, would you figure, what’s a few more years of conflict in the grand scheme of things, or would you not be able to off yourself quickly enough? Or would you just want enough time to get your affairs in order, maybe take out a HUGE life insurance policy and wait a couple years so you could get around the suicide provision? Or maybe you’d take just a couple days to explain your decision to your loved ones? What would you do with this information? Please be 100% honest and explain your decision. And just to make things more interesting, what if after you found this out, you were offered immortality, what then?
