Det beror på. Ibland är Batman ansvarig för att skapa superskurkar själv, ibland skapar han dem indirekt och ibland har han ingenting med det. Här är exempel på alla tre
I New52-serierna "Batman: Zero Year" han och Red Hood slogs och Red Hood föll i kemikalier vilket skapade Joker . Här är Batman personligen ansvarig för att skapa Joker

During this robbery he either tripped into a vat of chemicals, or was accidentally pushed in by Batman.
Bruce Wayne came to look in on Pamela's division when she took the opportunity to present him with a business project that would cut his advertising division by 100%. In fact, she had used pheromones to get the meeting with him, and this was her proof that Wayne Enterprises could use pheromones to target clients, and modify their behaviour to the company's benefit.

When Jonathan Crane was a child, his father conducted many experiments, trying to comprehend the emotion of fear. Unable to use proper test subjects, Dr. Crane used Jonathan as his guinea pig.As part of the experiments, Jonathan was locked inside a little dark room while his father examined the test's effects on his son. One day however, during one of the experiments, Dr. Crane experienced a heart attack and died, leaving young Jonathan still trapped in the pitch black test chamber.
As a result of this event, he was traumatized most of his childhood until, eventually, Jonathan decided that if he could control fear, he would never have to live in it again. He soon developed an obsession with his goal and became a psychologist with a concentration in phobias. Not waiting long to put his degree to use, Crane began using patients as test subjects to develop a project that he would later call "Fear Toxin". The gas, when inhaled, would cause his victims to hallucinate about their worst fears.
Crane, adopting the alias "the Scarecrow", soon became a threat to Gotham City, as he took criminal measures to perfect his fear gas.
