Heroes In Crisis by Tom King and Clay Mann was a series that turned Wally West, The Flash, into a mass murderer and, in the process, killed off Roy Harper and Poison Ivy. It was by accident, but he then decided that the best thing to do was to cover up the crime and pin it on Booster Gold and Harley Quinn while trying to make some of it right by leaking all the personal superhero secrets held by The Sanctuary, before handing himself in, and going to jail, though not before he was kneed in the bollocks by Harley Quinn.
He was later sprung as some kind of cosmic treadmill, and gaining the powers of a God in Flash Forward, who explained what happened was all because Wally West felt lonely, his wife and kids were taken away from him by changing timelines.
With Wally West suspecting that the multiverse was extracting karma from him, as well as a note to an abandoned storyline where he would have been reinvented as the superhero Penance to make up for his suns.
But what of his decision to cover up what had happened? Professor Thawne, the Reverse-Flash, repeatedly interfered in Barry Allen's timestream and those around him, using the power of the negative speed force, which has another power that Thawne takes full advantage of.
Whispering in the ear of all the Flashes across the decades, playing the role of the serpent, crawling on his belly at super speed.
