I guess that can be a test for the computer, if it can understand nuances of what is bad and what is good, then it is already on the way to become sentient...

That's a good point about Ultra series, the good characters at least have very clear motivations and ideals. The bad guys are usually just monsters, so they probably don't really think much about why they attack the Earth, they probably just want to eat.

Everyone is different in their approach to creativity... As for me, I'm just happy there are people who take time to post their fanfics online, otherwise I wouldn't have anything to read XD

That is completely understandable XDD
