"One less human. More room for the monsters to roam." That's how The Bride, the closest thing that Creature Commandos has to a sort of break-out character, justifies the eventual demise of Princess Ilana in the fourth episode.
To her, people are cruel and unstable, often falling prey to their own hubris and desires for power and love. And sure, the same can be said of monsters, but monsters are what The Bride knows, she understands that kind of chaos. And that's why The Bride was always destined to the leader of the Creature Commandos.
