Who is the Red हुड, डाकू now?

It's a little complicated.
When Jason Todd comes back from death his mad at बैटमैन for not avenging his death.
So he uses the Reh हुड, डाकू to try to get an emotional reaction from Batman.
Later he just acepts the role as Red Hood, being an "hero" who is willing to kill
