Dr. Jonathan Crane was mentally abused in school by bullies, many of which claimed he looked like Ichabod Crane from the Legend of Sleepy Hollow. This actually gave Crane a lifelong obsession with fear, and somehow weaponizing it. After being humiliated by a bully and rejected by a cheerleader, he shows up to the Senior Prom wearing a stereotypical Scarecrow costume with a gun. In all of this chaos, the bully gets into a car accident and is paralyzed permanently while the crash ends the life of the cheerleader. Still obsessed with fear, he earns a psychology degree and ends up taking a position at Arkham Asylum.
There, he performs many fear-inducing experiments on the criminals. He ends up perfecting the infamous “fear toxin” there and often uses it on others, including Batman, to avoid being caught. Utilizing fear forces people to see things that are not really there, as they see the very thing they are afraid of. Also, unlike the other Batman Rogues Gallery villains, Scarecrow is not committing crimes for money. Rather, it is for the ultimate thrill and power of making people fear for their lives. Of course, while he is smart, Scarecrow is also very experienced with multiple weapons and has shown impressive hand-to-hand combat skills too.
