Um, no? Because this is a comic book? I'm not saying that all comic books have to be PG, but to me this is like saying "does it seem simplistic and ridiculous that Wiley Coyote blows himself up and walks away every time?" Of course it is, but there are rules to every story-telling medium, and this is one that comic books have had for a long time. Even when the rules are broken and we have grizzly character death, stuff like Marvel Adventures pops up to counter balance it. It's really up to DC the direction they want to take the characters and the audience they want to reach. Personally, I'm perfectly happy with a "no-kill" policy, but if you want realism, I see how it can bother you.
