[SPOILER] Plot Discussion Thread *Spoiler Alert*

[Fortigurn]

In the end, as you activate the Harmonicas (if I remember the name well), the Machine yells "Kill him!"
Why would it want to kill Mandus, if this was gonna kill itself as well?

Spoiler below!

Either it's a plot hole (very likely, the plot isn't completely watertight), or it's all about the way Mandus dies; perhaps the sacrificial killing of himself in the temple is what ensures 'all of him' dies, including the double in the Machine.
