But, the algorithm itself isn't the same as the values I input into it.

What I mean by that is that I'm going "I think drug laws are unjust... THEREFORE I should refuse to convict in the case of a violation of those laws"

So is the "If I, personally, think a set of laws are seriously unjust, should I essentially ignore them when I'm a jury member?"

(note, my natural initial inclination was "yes, nullification of drug laws is a good idea", with the only question being "do I lie when asked in the first place if I'd be willing to convict on a drug offense or if I'd heard of nullification" etc... But once I got to thinking about it, to the actual algorithm I'm effectively running, well, hence my eventual asking here for advice)
