Hello!

Play as Deathstroke in the challenge maps and you'll see he doesn't use lethal force or leave a trail of bodies. Batman's aversion to killing makes him one of my favourite superheroes, but that style of vigilantism doesn't really work for Slade.

Why doesn't he kill anyone in the challenge maps? They could have added a new play style with killing enemies using his sword and firearms. Another example is losing a challenge map if someone kills a hostage. Why would Deathstroke care if a hostage dies or not? People dying is just the cost of doing business. Life (of other people) doesn't mean anything to Slade. It's stuck in my craw that they botched his character. Red Hood is just edge lord fuel, but Arkham Knight at the very least got his character down.
