I kinda like Mike Barr's take on Jason, but at the same time it occasionally reads so very, very odd. Take the panels where Jason - who grew up in Crime Alley - doesn't realize that Rhonda is a hooker.
And even the extract from 568 is entirely at odd with my view of Post-Crisis Jason, and this is where I disagree with you when you than with Jason, it's more about the fight than about the victims. Most of Jason's anger issues later in his time as Robin or after he got resurrected come from, I think, from his minding the victims, wanting to protect them and to get revenge for them. I'm absolutely unable to imagine Post-Crisis Jason thinking saving an innocent's life is not 'the important stuff'.
Seeing Jason do the normal Robin stuff of making sure Batman doesn't flip off the handle makes me a little nostalgic. If Morrison could be kind enough to refer to that through his Jason's bitter ranting, it'd excuse much.
