Thoughts on the scenario after completing "Hammers of Fate".

I think Faidaen did the right thing. Nicholas was not only strong, but also completely uncontrollable. And that could have led to unpredictable consequences...

But it depends on how you look at it. His "brain" remained the same; the only bad thing was that he was not a full-fledged necromancer, but merely a high-level vampire, which means his mind could be controlled by a stronger necromancer or someone else. It would be more correct to say that he was "not fully controllable."
