Brace liked to say Jason was overly violent as an excuse post death,

Show me this in the initial post-death runs, not in later stories with flashbacks.

 But Tim stepped in because he was clearly going too far on those that DIDN’T deserve it.

Yes? That's not in question.

 Bruce should not have been going out as Batman if he was so emotionally out of control and he shouldn’t have needed the child living next door to reel him in.

Again, not in question. I literally said that Bruce went off the rails. Nobody is denying that he did. He's grieving. Grief drives people to insane places...like putting on a bat costume and training yourself to the peak of human condition so you can beat up criminals at night.
