God will give him his just rewards, but many of us on earth will probably not live to see it. Maybe we can view in from heaven. Sometimes though I wonder if he won't be able to con God to, sacrilegious though that may sound.
Nope...God can't be conned, no worries.
Oh, I think we might all be here to see it. Three of my (cough, spit) relatives sent my grandparents to the grave. In short order they met with their own bizarre and surprisingly fitting deaths. One burned himself up, another suddenly developed a fatal health problem, and the third died of a heart attack at a young age.
