I think both of you are wrong, and that life runes are their own thing. Souls and blood are both associated with life, yes, but neither of them ARE life.
Blood is the physical representation of life and life-force, the medium which connects the mortal body and the immortal soul, transporting the life-force around the body. Blood gives life, as seen in childbirth, but its absence can also take away life, as seen in severe injuries. As long as the blood flows, it gives life to the physical body. Blood, however, can be without life: a dead corpse, once living, still has blood. So, blood is not life, blood is the intermediary between life and body, transferring the power of life to the body in a physical form.
Souls are the incorporeal or spiritual essence of a living being, the thing that gives the body life and animated the living organism. It's the eternal culmination of our being, which even after death exists and is able to think. It does not exist physically, like blood, as it can exist without a body, yet it is important for the well-being of the human being: absence of soul can very well lead to sickness. Soul, however, can be without life: after death, the soul is lifeless, clinging to the corpse, until its lingering connection to the body are cut and it can pass on to the Afterlife. So, soul is not life, soul is the culmination of a being that lives, and which continues to exist even after the being no longer lives.
So, if the soul is the culmination of the living being, and blood is the material that transfers the life-force to the body, then what is life? Life, simply enough, is the very essence of living: beings originating from material that had never lived. Keep in mind that I never said "dead material": dead material implies that the material would've come from something that once lived. Rock never lived, while soil did, as it consists of the decayed material of dead living beings.
