Unless the manga left out something from the actual page, it could have died in space. No guarantees that it's invulnerable in addition to being unaging, as the Foundation was unlikely to test too much for that.
@Fari Lawful in the sense that he follows his own code of ethics, twisted as they may be. Neutral/Chaotic Evil imo would be someone like Ainz from Overlord, who routinely breaks his own code.
It's been a while since I read the entirety of Re:Monster though, so I could be forgetting something...
I had to go back and read the first two pages, though that's not on the translator. It didn't hit me what those incomplete notes were until I started making the connection between the monster cores and the egg.
