A more thorough explanation:

Definition: An abuser is someone who mistreats or harms someone or something.

Examples:

• A person who physically or emotionally hurts their partner is an abuser.
• Someone who neglects or mistreats their pet is also an abuser.
• A company that pollutes the environment is an abuser of the planet.

The examples illustrate how an abuser can harm a person, animal, or the environment. It is important to recognize and address abusive behavior to prevent further harm.
