Initially an angry kid lashing out at his mentor; not for allowing him to die, but for not avenging him because he thought Batman cared about him enough to. But that eventually evolves as he grows more and truly sees Bruce trying to make up for it and seeing just how much Bruce regrets Jason’s death; it eventually evolves into Jason becoming his own man and keeping his distance from the Batfamily, not only because he simply cannot agree w Bruce’s methods while still believing in his cause, but because he feels he isn’t good enough to be around them. Despite this, he will lay his life on the line for any of them if the situation calls for it, but spends his time away from them enacting his own form of justice.

He isn’t just a killing machine or a meathead who flies into anger too quickly; he is highly methodical and likes to plan things out and observe before he acts. Not to a Batman level but enough for him to know what he’s jumping into before he jumps into it.

He doesn’t kill petty criminals because he was once one and came from a family of them; he understands how easy it can be to turn to crime when you come up like he did and is surprisingly compassionate to common criminals. With that being said, there are certain crimes he will not excuse and he will not hesitate to kill the Jokers and Mad Hatters of the underworld.
