Thanks for trying to answer, even though i must admit i don't understand the last answer.
For the other two, i know that bonding knife happens before modifiers and tormentor after modifier, but still effects don't interrupt, you can have multiple effects occure on one roll, else plasma weapons would not expolde on a natural 1, as the effect a 1 before modifiers misses, is also triggered. Or are you saying, that the natural 1 rule has also replaced the remaining process, and so the plasma cannot explode anymore because it is not a normal hit roll anymore? Or did i miss anything in your argumentation?
It boils down to does Tormentor overwrites the conflicting effects of the other rules, or if the other rules somehow forbid it?
I am not sure how GW planned it, and even though i was trying to find another similar case in the rules even before i put the question here, i have just now found one other similar problem, the stratagem of the obsidian rose vs tormentor, one rule states no one flees, the other says one model flees. So the effect is quite similar, but this time the order is the other way around, the stratagem is used after the roll so after tormentor, and i am pretty sure GW wants it to overwrite tormentor and anything with similar effects.
But i also don't see any reason for it to overwrite, except for common sense, in real life and in informatics the last one would win. But common sense is not always used in 40k rules.
