@ArdainianRight A tribal alien race is converted to Catholicism by the human colonists. This alien species depends on a virus in order to reproduce, but the virus is deadly to humans. The alien species is also able to live pretty much forever because they can "die" and turn into a tree. So they think they are morally superior to humans who are cursed with original sin and actually believe that they were chosen by God to bring Judgement Day so they attempt to hijack starships in order to spread the virus to other human colonies.

@xianc78 In this hypothetical sci-fi future all the humans who stayed on Earth turned into soulless tranny coomers living in a cyberpunk dystopia, and all the people seeking an actual human existence left to colonize space, so you could argue in such a case that wiping out all the humans on Earth would be justified and positive.

@ArdainianRight They wanted to wipe out ALL of humanity. Humanity also previously genocided a different alien species, so it is believed that humans aren't just sinful but downright evil and God doesn't forgive them.

@xianc78 We'll deal with that when we come to that bridge. Either way whichever civilization colonizes space first would be literally light-years ahead of whatever planet they might visit, so I'm not super worried.

@xianc78 @ArdainianRight I'll have to add that to my reading list!

@KryptoBlok @ArdainianRight It's a sequel to Ender's Game and Speaker for The Dead. Make sure to read those first.

Theoretically aliens if exist they wouldn't be subject to original sin. Dolphins are highly intelligent, but most concepts of Christianity wouldn't apply to them if we could somehow talk on a equal level.

@LodedDiaper @xianc78 Maybe, maybe not. If the aliens have religion, then that would be a strong indicator that they have souls capable of conversion.

I think if there other forms of life that practice religion, assuming they didn't sin they would be Christian. Otherwise I don't know how Jesus's earthly sacrifice would apply to them.

Then again that's ignoring how we define "alien", for all intents there parts of the sea still as alien as other planets. And going beyond the physical realm, the angels are mostly alien to us beyond the physical forms they took on earth.
