After defeating Chapel but choosing to spare him—marking the first time Wolfwood truly adopts Vash's "no-kill" policy—he is betrayed by Legato Bluesummers, who controls Chapel to shoot Wolfwood. Key Themes and Symbolism
Wolfwood's death occurs precisely because he tries to follow Vash's morals by sparing Chapel. His final moments are spent lamenting that he realized too late that a different way of life might have been possible.
Wolfwood, a priest who carried a literal cross, dies inside a church. This is often interpreted as him making peace with God and seeking forgiveness for his past sins.
