To all catholics and pro-li..

would you consider it a sin against god to abort an alien parasite like in the movie aliens?

They are alive and have souls- should that be illegal?

I want to start by saying that I don't believe in aliens, so this is pretty much just an exercise for me.

The questions you are having me answer are "what is life?" & "what is a soul?" The reason the Catholic Church is against abortion is that it believes that "human life" (so right now, aliens are a moot point) begins at the very moment of conception. This can be an arguable point for most people, but not the church. Sorry, that's just the way it is right now. Next, you are asking me to define a "soul." Good question and one that would take up too much space here, so I'll just say that, for the sake of argument, these aliens you are talking about have souls. From there and assuming that aliens existed and had souls, sentience, etc. I would say that aborting an alien parasite would be murder.

Now, I have also never seen the movie "Aliens" (*yawn*) so for all I know, you are talking about a "murder in self defense" issue instead of a simple abortion. From what I can guess, this isn't the same as a woman getting pregnant - this is another body being forced upon a human body. If that were the case, it would be between the person and God, as most things are anyway.
