Arguments for Kyubey being evil:
* Deception and manipulation: Kyubey presents itself as a benevolent being offering wishes to girls in exchange for their magical powers. However, it intentionally hides the true nature of the contract, which involves becoming a magical girl and fighting witches, a potentially deadly and soul-crushing task.
* Exploitation and disregard for human life: Kyubey prioritizes its own goal of collecting energy from witches, even if it means sacrificing countless human lives. It shows little remorse for the suffering and death it causes, viewing magical girls as expendable tools.
* Lack of empathy and compassion: Kyubey lacks understanding or care for human emotions and experiences. It sees humans as mere instruments for its own purposes, failing to acknowledge the devastating consequences of its actions.
Arguments against Kyubey being evil:
* Logical and objective perspective: Kyubey is a creature of pure logic and objectivity, devoid of emotions and morals. It operates based on its own understanding of the universe and its perceived need to maintain balance.
* Lack of intention to harm: Kyubey doesn't actively seek to cause harm to humans. It offers a contract, and the choice to accept or decline is ultimately up to the magical girl. While the contract has severe consequences, it's not intentionally designed to inflict pain or suffering.
* No concept of "evil": Kyubey might not understand the human concept of "evil" as it operates based on a different set of rules and motivations.
Ultimately, whether Kyubey is "evil" is open to interpretation. Some might argue that its actions, even if driven by logic and necessity, have devastating consequences for humans. Others might see it as a flawed but ultimately neutral entity acting within its own understanding of the universe.
