Doubtless he could've foreseen, and prevented himself from, being shot by Creedy and his henchmen who "swept the place clean". Even as they shoot him, V just stands there until they run out of bullets. Only after, V starts throwing his knives!
Why? V could've thrown his knives as soon as they started shooting, and mitigated the gun wounds on V that proved fatal.
Before arriving at that basement (what's the correct term?), he could've armed himself with a gun, then use it to shoot back.
