The answer is Cain. He killed a quarter of the world's population.

[lyn1982]

"But the Lord said to him, “Not so[e]; anyone who kills Cain will suffer vengeance seven times over.” Then the Lord put a mark on Cain so that no one who found him would kill him. 16 So Cain went out from the Lord’s presence and lived in the land of Nod,[f] east of Eden.

17 Cain made love to his wife, and she became pregnant and gave birth to Enoch."

If Adam and Eve were half the worlds population, and Cain and Abel the other half, who was Cain making love to?

This is a reply from AI to your question:
According to the Book of Genesis, after the birth of Cain and Abel, Adam and Eve had other children. Genesis 5:4 states, "After he begot Cain, Abel, and Seth, the days of Adam were eight hundred years; and he had sons and daughters".
Therefore, Cain and Abel were not the only other humans besides their parents. Cain would have married and had children with his sisters or nieces, as the early generations of humans in the biblical account were the only people on Earth and intermarriage was a necessity for the population to grow.
