Abel

Abel was the brother of Cain.

Although originally thought of as God's favorite, Cain revealed that Abel was in fact talking to Lucifer. In an effort to protect his brother from corruption, Cain offered a deal. Cain offered himself to Lucifer so that Abel would go to Heaven instead. Lucifer agreed, on the condition that Cain himself would send his brother to Heaven. Thus, Abel was struck down by Cain. Abel was taken by Heaven, while his older brother became the most terrible demon to walk the earth.
