There was/is only one human who was/is truly immune to the temptation of the ruinous powers, but fighting against these powers that human is failed. Now he is half dead, half a guiding consciousness to mankind,and maybe half the way to become a true god. The clones of this very man, the primarch's was corrupted and turned against each other.. Half of them become traitor and killed the other half (more or less). The clones of the clones the emperor finest soldiers was also corrupted... Brother killed brothers and when the dust sat down half the legions was under the influence of the ruinous powers.
So regarding that there should be a chance not to be corrupted not immunity against it.
- In the top of the most loyalist iceberg there are the Grey Knight's of course with a resist like 90%
- under that there are the fan-girls of the emperor the adepta sororitas, the inquisitors, and other very dedicated individuals chaplains, priest's with exceptional faith and such others resist like 75%-80%
- the mid section could be the orphans of the Schola Progenium and the Adeptus Astrates. They are fostered to be loyal and be living icons of the imperium among others in faith. Resist is around 60-65%
- the lower section is the dedicated and loyal servents of the imperium: Adeptus arbites, Guardsmans, some rouge traders, adepts and others Resist like 40-50%
- In the water level there are the vast billions of regular, everyday citizens of the imperium, and of course the weak willed servants from the above level(s) resist could be 20-30%
- Under the water you can find the scums of the imperium who can be miserably low both on intelligence and will power or be a criminal but not corrupted ( so far), pirates, hive gangers, and other criminals, corrupt (as a criminal) officers, adepts and the likes resist is like 10%-20%
To corrupt someone could take time but demons and chaos gods has all the time they need.....
