What was the symbolic significance of Wolverine's 'crucifixion' in the 'Death of Wolverine' storyline?

The symbolic significance of Wolverine's 'crucifixion' is profound. It underscores his suffering and sacrifice, positioning him as a Christ-like figure enduring extreme pain for potentially a greater purpose or the culmination of his arduous life. The X-shape itself can symbolize his connection to the X-Men and the mutant cause he fought for. It also emphasizes his vulnerability without his healing factor, elevating his final struggle and death to a tragic and almost sacred event, marking the end of an era for the character.
