Star wars what if...(sorry about bad quality just click on the link)

From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainty of steel. I aspired to the purity of the Blessed Machine.
Your kind cling to your flesh, as though it will not decay and fail you. One day the crude biomass you call the temple will wither, and you will beg my kind to save you.
But I am already saved, for the Machine is immortal...
...even in death I serve the Omnissiah.

Praise br to the machine god

Steel may be strong, but it is anything but certain. Steel must be animated by hydraulics if it is to have the strength of movement. These hydraulics are anything but strong; if a single bullet was to go through the engine powering this steel, the steel would cease its animation. Plus, if a single hydraulic line gets fractured in the steel, the fluid will leak and the animation will also cease.
Though flesh is less strong, it is much more certain. Flesh is smaller and more nimble than steel; flesh can hide when need be, flesh can stay behind cover when need be. Steel cannot do that. Not to mention that flesh can take advantage of steel without the weaknesses of steel. Small Rockets are able to completely disable steel.

Let me tell you, the Mechanicus would not be happy with that person.

The Mechanicus is dying as soon as a bullet strikes his hydraulic lines or engine.
