Their not showing the character in the worst way possible. They're paying homage to the character's most traumatic and defining experience etc. That's like saying showing Jason Todd blown up and beaten the crap out of in a cover is the worst possible way of showing the character on a cover despite that moment being a pivotal event in his career: his death.
Except for instead of showing her overcoming or facing her trauma, is JUST shows the trauma. The narrative of defense that it was out of the trauma that she grew stronger is maybe worthwhile, but this picture JUST shows her in a state of horror, panic, terror. There's not hope there, just the moment of actual fear.
Worth noting, they have not released the art of the Red Hood/Arsenal #1 Joker variant. What do you wanna bet it's just a picture of teenaged Jason Todd beat to a bloody pulp? I wouldn't hold my breathe.
