Arguments for:
* Caturamon's Mysterious Nature: Throughout the series, Caturamon remains shrouded in mystery. We don't know much about his past, motivations, or true allegiance. He appears to be a neutral party, but his actions could be interpreted as manipulative or secretive.
* GranDracmon's Manipulation: GranDracmon is a master manipulator and is shown to be able to influence others to do his bidding. It's possible he could have subtly swayed Caturamon towards his own agenda.
* Caturamon's Powers: Caturamon possesses powerful abilities that could be useful to GranDracmon. His control over digital energy and his connection to the Digital World could potentially aid GranDracmon's plans.
* The Digital World's Instability: Caturamon's actions, particularly his involvement in the "Digital World Collapse" storyline, could have been orchestrated to further destabilize the Digital World, playing into GranDracmon's desires for chaos.
Arguments Against:
* Caturamon's Benevolent Actions: Throughout the series, Caturamon is shown to be helpful and supportive of the Tamers, even aiding them in their battles against other Digimon. This contradicts the idea of him secretly working for GranDracmon.
* GranDracmon's Focus on Chaos: GranDracmon primarily aims to sow chaos and destruction in the Digital World, while Caturamon's actions, while sometimes leading to unexpected consequences, generally seem to be directed towards preserving the balance of the Digital World.
* Lack of Direct Evidence: There is no clear evidence in the show that Caturamon is working for GranDracmon. His actions could be explained by other motivations, such as his own personal goals or a desire to maintain order.
Ultimately, the question of whether Caturamon was secretly working for GranDracmon is a matter of speculation. While there are elements that could support the theory, the lack of direct evidence and his overall benevolent nature make it highly unlikely.
However, it's a fun thought experiment that allows fans to analyze the characters and their motivations in a new light.
