re: Ending of TDKR Question: Robin Related (SPOILERS)

It doesn't really matter because regardless of who he became, he wouldn't have lasted a year running around trying to stop gangs of thugs, let alone criminals like the Joker or Bane. Bruce was able to take them on because he was trained extensively by the League of Assassins. But that Robin was just some disillusioned cop whose only training was at the local police academy. He would've been in a morgue within a year.
