Here are some examples of how "diabolic" can be used:
* "The villain's plan was a diabolic scheme to take over the world." This implies the plan was extremely evil and cunning.
* "The prisoner was accused of committing diabolic acts against humanity." This suggests the crimes were horrific and inhumane.
* "The artist's work was filled with diabolic imagery." This implies the art contained depictions of evil or demonic figures.
Important Note: While "diabolic" is often associated with the Devil, it can also be used to describe something that is simply very wicked or cruel, even if it doesn't involve supernatural beings.
