It's a spin on the origin mythology.
Lucifer wanted Abel. Cain didn't want Abel to get tempted by Lucifer. So Cain made a deal with Lucifer to protect Abel's soul. Part of the deal was that he had to kill his own brother. In turn, Lucifer now has Cain as a demon. The first blade (the bone) was the weapon Cain slew Abel with.
So lucifer is suppose to resemble Crowley and Cain- dean?
Death is the skinny lookin old dude with a cane right? He's always shown near a fireplace
