Not to mention the known effects of using the Lazarus Pit = homicidal. I'd imagine after the Lazarus!crazy wore off (if it actually does, not sure) you'd see a decline in the sheer amount of rage for Jason. I think he'd still have tons of issues that would make a violent and angry young man, but I would think you'd see an even more cunning Jason instead of the out of control personality he sported in BftC. As much as I liked Winick's writting of Jason specifically (he's the only one who handled him with even the slightest bit of understanding for the character) I do not support his depiction of Batman or Nightwing upon Jason's resurrection. From what we have seen in post-Jason stories where villains (Neron in particular) taunt Batman with the idea of Jason coming back, you'd think that once his initial mistrust of Jason's identity was gone (when Jason proved he was in fact Jason, giving Batman the DNA samples he needed) he would have really stopped at nothing to have Jason back into the fold (Batman, for all his harsh impersonalization, would never let someone he cares about just tear off on a killing spree or even be let out of his sight if only for tons of examinations to find out why they came back = think of Oliver Queen's resurrections and Batman going over him with a fine toothed comb while he was unconscious) But instead we get unrealistic reactions form both Batman and Nightwing (Nightwing may not have been super close to Jason, but Dick's a marshmellow when it comes to family, he wouldn't abandon someone he cares for either no matter what they've done = think Bruce Wayne: Fugitive story arc) The fact that there wasn't a redemption story arc of some kind while Bruce was still alive and kicking is a huge f-up on the part of the writers and/or editorial. You could have milked this concept for two complete arcs: Jason's redemption then Jason trying to get back into the 'family business' and finding out who he is. You could make a another where he goes evil again (the writers love to do stuff like that, look at Raven and Jericho) Jason's character is complex - there's a lot that could be done with him finding out who is apart from the Batfamily - coming to terms with what he's done and if he feels any remorse - and with what a f-cked up childhood this guy must have had before and after Bruce found him. But I suppose that would take too much effort for the writers/editorial folks nowadays to write a successful look at Jason instead of using him as a evil crazy measuring stick for the other boys to work off of.
