10 Worst Things The Flash Has Ever Done
1. Trapping Inertia In A Time-Based Hell - All Flash #1
In a move straight out of a horror movie, All Flash #1 sees our hero, Wally West, trap the young villain Inertia in a hellscape where he cannot move, and is only able to blink once every hundred years.
Inertia is still thinking in real-time during all of this, meaning he's driven slowly and surely insane, making this an incredibly messed up thing for a supposed superhero to set up.
Admittedly, the kid did kill Bart Allen - and then taunt West about how his sidekick died - but Inertia had been raised to hate the speedsters his entire life, meaning his cruelty was learned from others, not inherent in him.
While this doesn't excuse his actions, it does mean that it potentially would have been possible to reform the teen with the right help, instead of torturing him for doing the thing he had been taught to do since birth.
