Honestly I don't blame Jason at all for wanting to kill Batman, Bruce found Jason in the first 10 minutes of searching I forget why g didn't just go get him ik he had a reason but Jason wasn't having any of his shit I'm talking about the Arkham story line
He was too late??? It blew up as soon as he got there. Also Jason didn't blame Batman for his death but he was angry that Batman didn't kill Joker after his death so he killed him himself. He never wanted to harm Batman.
