Spoilers for Superman: Space Age #2 by DC ComicsGreen Arrow is pointing out the biggest flaws with a no-kill rule on the Justice League, as the team assembles for one of the first times in an alt-universe story. In Superman: Space Age #2 by DC Comics, Oliver Queen questions Wonder Woman trying to implement a no-kill rule on the superteam, saying that it's impossible to ensure that everyone lives in the high-stakes world of being a hero - and he's right.

While Batman might have killed in his very first issue, the hero would be among the many Justice Leaguers who have implemented a no-kill rule, even in the most dangerous scenarios. From Green Lantern, The Flash, and Superman, the greatest heroes in the DC Universe won't kill unless there is simply no other choice - and The Dark Knight's no-kill rule is even stricter, as he won't do so under any circumstance. However, in a new comic, when the Justice League assembles for the first time, Green Arrow points out the biggest flaw in implementing a no-kill rule: It's pretty much impossible.

In Superman: Space Age #2 by Mark Russell, Mike Allred, Laura Allred, and Dave Sharpe from DC Comics, Batman and Superman join the Justice League in the first meeting of the superteam in the recently built Hall of Justice. Superman tells his fellow heroes that they need to lay down some basic principles and what they should and shouldn't do, with Wonder Woman saying that "not killing people" is an excellent place to start. Green Arrow openly scoffs at the suggestion while admitting the biggest flaw with the no-kill rule: Justice League heroes kill people every day based on who they decide to save and not save.

The Justice League's No-Kill Rule Is Impossible To Implement

Justice League No Kill Rule Questioned

While the Justice League can implement a no-kill rule among the team, Green Arrow correctly points out that the team inadvertently kills people every day based on who they decide to save. Choosing who to save in a life-or-death situation is one of the greatest hardships of being a superhero. Sometimes, everybody can't be saved, and tough decisions must be made. Therefore, having a strict no-kill rule is impossible. Ultimately, Green Lantern compromises with Oliver Queen by changing the principle to "try not to kill people."

If the Justice League could, they would save everyone. However, given the dangerous situations they often find themselves in, that's not always possible. As a result, the biggest flaw in enforcing a strict no-kill rule is that it can't be followed due to inevitable collateral damage, even for a team as powerful as the Justice League.
