Re: In hindsight what changes would you do - Part 1
Even in TDK Bruce seemed a bit off...trying to spit out the word submarine where Fox had to help him with. Those "poor choice of words" of Joker letting Rachel go. Running straight into Joker when he should've been smarter to not even let Joker get in his head that quick in the game, letting Joker go when he should've focused on Joker ever since the ending of BB when Gordon brought him up(seriously, Bruce should've thought it was a pretty big deal when Gordon brought it up in their "first meeting").
The best part of TDK, the final battle, is when Batman actually seemed to really be this intelligent beast in how he handled the SWAT, the hostages and Joker's goons all at once.
But, building the sonar device doesn't make him wise. He was simply paranoid it seemed to built such an unethical machine.
