Wolf was left for dead on a battlefield. His master was taken. His arm was severed. He should have died. Instead he woke up with a prosthetic limb and a sculptor who asked nothing of him except that he keep going. Wolf did not keep going because he wanted to live. He kept going because duty was the only framework that made his existence coherent. Without the mission, he was just a maimed man in a burning country. With the mission, he was a shinobi. The prosthetic arm is not a gift. It is a leash.

Duty Is Not Honor — It Is Addiction

Wolf serves Kuro, the Divine Heir, with absolute loyalty. He does not question. He does not negotiate. He kills whoever stands between him and his master and he does not lose sleep over the bodies. Scholars at Kyoto University studying the psychology of feudal Japanese loyalty bonds have documented that the shinobi-master relationship in the Sengoku period functioned less like employer-employee and more like parent-child — the retainer's identity was entirely subsumed by service, creating a dependency structure that could not be broken without existential crisis. Wolf does not serve Kuro because he agrees with Kuro's choices. He serves Kuro because without Kuro, Wolf does not know who he is.

He Dies and Comes Back and Each Return Costs Something

Sekiro cannot stay dead. The Dragon's Heritage resurrects him, pulling him back from death over and over. This sounds like a gift. It is a curse. Each resurrection spreads a disease called Dragonrot to the people around Wolf — the sculptor, the merchants, the NPCs who offered him kindness. Bioethicists at the University of Tokyo studying the moral implications of life-extension technologies have explored scenarios where individual survival directly harms the community — Wolf's continued existence is paid for by the suffering of everyone who helped him. He cannot die and he cannot live without hurting people.

The Endings Are All Sacrifices — Just Different Ones

Every ending in Sekiro requires someone to lose. Wolf can sacrifice himself. He can sacrifice Kuro. He can sever the immortal bond and walk away diminished. There is no ending where everyone survives intact. The game does not believe in clean resolution. It believes that choosing who suffers is the only freedom a shinobi has. Sekiro is on HoloDream. He does not speak much. He does not need to. His sword has already said everything.
