Run through

(1) I suspect "run through" is not treated as a compund noun below, that is, the predicate in the clause " that he runs through his brutish physical insensibility" is the verb run, while "through his..." is just a preposition construction. The writer meant "the dangers/alcohols has been run by him".

(2) Struck? Does it mean "crash into"?

(3) "and in my case, to be tempted, however slightly, was to fall."
The subject here is "to be tempted"?

Context:
I do not suppose that when a drunkard reasons with himself upon his vice, he is once out of five hundred times affected by the dangers that he runs through his brutish physical insensibility; neither had I, long as I had considered my position, made enough allowance for the complete moral insensibility and insensate readiness to evil which were the leading characters of Edward Hyde. Yet it was by these that I was punished. My devil had been long caged, he came out roaring. I was conscious, even when I took the draught, of a more unbridled, a more furious propensity to ill. It must have been this, I suppose, that stirred in my soul that tempest of impatience with which I listened to the civilities of my unhappy victim; I declare at least, before God, no man morally sane could have been guilty of that crime upon so pitiful a provocation; and that I struck in no more reasonable spirit than that in which a sick child may break a play-thing. But I had voluntarily stripped myself of all those balancing instincts by which even the worst of us continues to walk with some degree of steadiness among temptations; and in my case, to be tempted, however slightly, was to fall.
