Around 6 million Jewish people were killed, and to compare the amount of kiling in war today would be very different from war in the past. mainly because there hasn't been a recent genocide.
By God, Gold, and Glory, I assume you mean them as three reasons for exploration. Spreading monotheistic religion (I.e. God) was a common reason for exploration due to the large influence religion (especially Christianity) had on people. Many explorers were missionaries, who attempted to convert people from all over the world to their religion. Secondly, gold (or wealth) was another reason for exploration. Everyone in the past wanted wealth just as much as people today wanted wealth, so the promise of it was almost certain to get people to go and explore (see the California Gold Rush as an example.) Finally, glory was the last major reason for exploration. Everyone wanted to be famous for something as much as people today do, and what better way to do that than to discover a place not yet documented on a map? People who got back form exploration alive were often treated as heroes, mainly because of the kinds of things they had to endure during their trip.
