Yeah, if he kills Thawne, he will create Flashpoint again. So, Scareface Barry doesn't go there, but goes to the best spot in his past life that will least affect on the timeline, but stop all the harm he might do as Flash later. He might hate himself so much, that he doesn't care if he dies as a result.
