Lore ahead. Where is it said that they cherish all life? Considering they left the Protoss in the middle of a nasty civil war with nothing more than an "Oops, our bad!" seems to contradict that. Regardless, you assume that the threat posed is a direct battle threat. They could simply be coming back to finish their experiment which could have some very nasty implications. You seem to be idealizing the race for some reason, but the lore points to them viewing lower species as little more than toys. |
My friend's book. I can find you the quote online I bet.
I also agree that they don't do mcuh for other races other than observe them, but they would never be a "threat" that kills other races. From the perspective of the SC1 game, there is absolutely zero reason for the Xel'Naga to be any form of bad. I also wish Blizzard hadn't pussied out and made them a playable race, them or those hybrids.
