Nah, he wasn't an older, angrier Nate Grey - he built Providence and tried to end all the ills in the world....and then he sacrificed himself to try & unite the world. Having survived this, he later said that the TO virus is part of his DNA & so can never he fully eradicated. His blood also has something to do with Apoachips' resurrections & I didn't read enough of X-force to understand how Hope manage to eradicate the TO virus.
