Kain alive without a heart.
This has puzzled me for a while. When Raziel ripps out the heart of darkness from Kain, he is still alive later on. Why? The main explaination circling around the net is "because he is the scion of ballance" which I find kinda...not satisfactory. Could it be because prior to the fight (which I think Kain would have won if he WANTED to fight) they both state that the other one has "the only weapon that can kill me" and since Raziel did not use the spectral soul reaver Kain lives on even without the hear which was not his in the first place.("I was always considered heartless". ;o) )
Can't wait for the next game! But I will anyway. ;o) Kain is easily one of my favorite characters ever.
