All bloodlines of man, while some  better than others, is actually all wicked! Only the blood of the messiah, Jesus of Nazereth, is actually truly Good. By Who's standard you ask? Our Maker who deeply loves his creation and only wants the best for us! The one who Loves righteousness and Hates wickedness!

 John 6:53:And Jesus said to them, I assure you, most solemnly I tell you, you cannot have any life in you unless you eat the flesh of the Son of Man and drink His blood [unless you appropriate His life and the saving merit of His blood].
