A patient was oscillated between life and death. In the Operation Theater, Doctor wore his dress and saved her life by using surgical instruments.

At the same time, in the secret chamber, a serial killer wore his mask, and tortured a girl by using same surgical instrument and murdered her.

(Both are using same instruments, one is saving lives and another is killing.

An instrument doesn't define a person, but how we utilize them that definitely do define that person)
