A Few Questions About the Manpigs

[Alardem]

There's a theory going around that Mandus is technically invincible due to being imbued with the same Compound that revives the Pig-Men - this is supported by the Iron Lung at the end being filled with the liquid, by having Mandus talk about 'blue water running' in his veins, and by the text talking about the chemical allowing for dogs and severed heads to revive (Agrippa reference?) If this is the case, then it could be that he simply can't die - the Machine is doing its best to delay him, not murder him.

Also, if we consider that the Machine is linked to Mandus and the latter's heart is powering it, then it'd be in the Machine's best interests to keep Mandus alive. The ending in which Mandus approaches his heart and electrocutes it depicts the moment in which he finally is capable of dying.
