Harry the last Horcrux

According to my understanding of the Horcrux process: First you have to
commit murder in order to split your soul.  Then there is a spell to be done
in order to place the piece of soul into an object.  Although Voldemort had
just committed murder (James) he was in the process of another killing AK
spell (green light) which rebounded off Harry.  What was left of him was too
weak to start casting spells (all he could do was take over the bodies of
the lower forms of life - GOF) Lily's sacrifice was born of love and left
something in Harry's blood that cannot be seen which protects him from
Voldemort.(PS)  Surely the love would not have tolerated something in Harry
as evil as a bit of Voldemort's soul (after all - Quirrell could not bear to
touch him after he was possessed by Voldemort.
