It's a trait that I've found in the comics themselves and I can't help but feel it stems from the work that was done in A Lonely Place of Dying
. I can accept the argument that at this point in time, having lost a Robin as violently as he did, Batman's in a bad spot. Here comes Tim Drake - a level headed kid who is taking complete responsibility for whatever might happen to him - offering to help him out. I don't like the idea of a crazy Batman, but I'll concede that at the nadir of his career, Batman might be acting as irrationally as Wolfman decides he should be. However there's a line (a thought, actually) in Batman 442 delivered by Dick Grayson that really set a bad precedent. "Bruce, for once think with your heart, not cold logic". Retroactively, Wolfman is establishing that far from Batman's actions being out of character since Jason's death, Batman has always been a cold, emotionless creature. You could argue otherwise but you'd be arguing with Dick Grayson. Interestingly, in a nice moment in his story Wolfman contrasts Batman as he was with both Robins by showing him as a proud, smiling fatherlike figure when photographed with Dick Grayson juxtaposed against a much sterner figure in pictures with Jason Todd. So Wolfman himself wouldn't seem to buy Grayson's presentation of the facts, but still...who would be a greater expert on how Batman relates to his Robins than Dick Grayson?
"You ask why I want to make Dick Grayson my ward? You ask it as if this were some momentary whim a well known playboy has decided to make. We all know my reputation and I don't deny that some of it is probably well deserved but this is no whim. My parents were killed by criminals as were his. I know what it's like. I know the loneliness. The fears. The nightmares. I know it all. Nobody understood when it happened to me. Nobody understood what it does to you but I do. I watched as his parents died and my heart went out to him."
Wolfman's own writing in Year Three. And THAT's why Bruce Wayne (not Batman) adopted Dick Grayson (not Robin). Grayson's "for once think with your heart" is extremely cold but goes unchallenged here and in later appearances. It seems to have become accepted fact that Batman's sole purpose for taking in Robins is to recruit soldiers in his war on crime and it's a take that has led me to really despise the creature he's become.
