So when Malthael doesnt kill Tyreal its because of the fact that there was no demon within him, and Tyreal doest try to stab Malthael but it goes through him. So with that no one can kill him? So later on as the Nephalem you have to become like Malthael to be able to face him. Does this mean Malthael could have just walked up to you and killed you sense you wouldnt be able to fight back without the spirits? Or am i seeing this in a wrong way?
Pretty much yes. Suffers from video game boss syndrome, like many others you see boss at the beginning they write you off as a weakling and continue on their buisness. At point it matters most, you have gained the power you need and will be able to defeat said boss.
