That's a really simplified way of explaining it. The original Reverse Flash or Professor Zoom was a lifelong Flash fan from the future who duplicated the original accident that gave Barry Allen his powers and then time traveled into the past to meet Barry. He went insane when he arrived in the past and discovered that Barry was not everything that he had built him up to be and that he was destined to become one of his heroes greatest rivals, only to die at his hands.
The second Reverse Flash or Zoom was a detective who made a critical mistake in the line of duty that caused his father-in-law to be murdered, his leg to be injured, and his marriage to fall apart. Years later, while assisting Wally West an accident with Gorilla Grodd left him paralyzed from the waist down. He went insane after he asked Wally to allow him to time travel and fix his mistakes, which Wally promptly rejected. Instead of gaining identical powers to the Flash, Zoom was involved in an accident with the Cosmic Treadmill which gave him powers over time rather than speed. Zoom's whole MO became the idea that he wouldforce Wally to become a "Better Hero" by giving Wally real tragedies that Zoom felt that he lacked.
