He's made mistakes, and his actions have had serious consequences, but those have still "just" been mistakes. In the DCU, morality and intention matter a lot more than the end results (at least most of the time), so heroes get a free pass for screwing up even if it costs lives.
2. All that said, yes there should be more accountability (from within the heroic community if nowhere else). Even setting Flashpoint aside, because that wasn't really on Barry, we've got stuff like Superman sending millions of people into the Phantom Zone for a year because an experiment went wrong. Batman's responsible for the entire earth being swallowed by the dark multiverse (everyone's lived on a copy since Metal) as well as breaking the friggin Source Wall. Barry and Wally destroyed the 25th century during Flash War, broke the speed force away from its position in the cosmic hierarchy, and broke open a barrier keeping some of those forbidden energies contained. Hal succeeded in destroying all of space and time (only to have history unfold in largely the same way it originally had but he still destroyed everything) in Zero Hour. And yeah, these guys operate on a level that is so crazy and ridiculous, stuff like this really is the lesser evil, the best possible outcome, or whatever. But yeah, these guys get away with a whole lot more than they rightfully should. Even Jason Todd gets to hang out in the Batcave, despite being a mass murderer who has done far worse than some of Bruce's biggest recurring villains. Why? Because they're heroes, and that justifies a lot of crappy behavior, apparently.
Really, the heroes are often responsible for more damage than the villains could ever hope to achieve. But, its DC and the morality of the world is black and white. Heroes get away with it. Villains don't. Because the heroes, even when they f**k up so royally they destroy worlds, have good intentions.
