Watching Sasuke's fights after the curse mark takes hold is like seeing a switch flip. The demonic influence doesn't just boost his raw power; it rewires his entire combat calculus. He's always been a tactical genius, but the edge turns jagged and desperate. You can see it against Itachi, where his precision is laced with an almost suicidal aggression, trading caution for overwhelming force in a way pre-curse Sasuke would have calculated as too risky. It amplifies his inherent willingness to sacrifice, pushing it into self-immolation territory if it means landing a hit.
That demonic chakra also seems to broaden his tactical palette in unsettling ways. He starts incorporating more brutal, close-quarters techniques that feel less like the Uchiha's elegant taijutsu and more like a cornered beast lashing out. The cursed seal's transformations themselves become a tactic—a sudden, violent surge in speed and strength meant to overwhelm and disorient before the opponent can adapt. It's a crutch, but a lethally effective one that warps his fighting style from a controlled, revenge-focused blade into a chaotic, all-consuming fire.
