Even Apocalypse himself had no solution to this problem.
The Winter Soldier was Captain America's closest friend. Either would take a bullet for the other.
Unless Apocalypse killed Captain America, he would never agree to eliminate Bucky Barnes.
And Iron Man's parents had been murdered. There was no reconciling a blood feud like that.
With that in mind, Apocalypse glanced at Captain America. What if I kill Bucky without him knowing?
Seeing Apocalypse stare at him without speaking, Captain America looked puzzled. "Does this problem have something to do with me?"
"Yeah..." Apocalypse sighed, then finally said, "The only Winter Soldier still active is Bucky Barnes. What do you think?"
"Impossible!" Captain America exclaimed. "Even if Bucky's alive, he'd be close to a hundred by now. How could he still be killing people?"
"Steve, you weren't the world's first super-soldier. If you could be transformed, why couldn't someone else? Including Bucky."
"That..."
Captain America fell into deep thought.
The first supervillain he had encountered was Red Skull.

His closest friend had become an executioner. Captain America had no idea what to do.
"I don't believe Bucky would become like this. Hydra must be controlling him," Captain America said.
"You're right," Apocalypse said. "He is being controlled. But does that mean he bears no responsibility at all? What are you going to do with him?"
Even a kitchen knife used
