For anyone who remains bothered by the death of Ted Kord, the Silver Age Blue Beetle, in the recent "death-tastic" crossover 'Infinite Crisis', there's an easy 'get out of jail free' card in recent continuity. When Blue Beetle joined the SuperBuddies a few years ago (don't ask--no, really, just don't, it's a textbook example of You Probably Don't Want To Know), the team traveled to a parallel universe and met their own evil counterparts. Except for Blue Beetle, whose evil counterpart was strangely absent. Oh, and he suffered a mysterious bout of amnesia during that story.
So there you go. The Blue Beetle that Max Lord shot was the evil counterpart, who had taken the opportunity to swap places with his good version when they passed through. In our universe, he had started to take his first steps towards redemption, inspired by the heroes of this world...and it cost him his life.
Actually, that's even more depressing than the version that DC published.
