I'm saying he can't control the power level of tsukuyome. there's no such thing as a "weak" tsukuyome, since in it's basis it's a genjutsu that pulls it's victim into a genjutsu world that the caster has full control over. Whether Itachi uses it to make a single copy of Sasuke have his eyes gouged out or whether he uses it on 100 Kakashi copies to torture them doesn't matter, because in both cases he's doing the exact same thing.

If he hadn't resisted tsukuyome, then he would've just done the same as the previous times, namely taunted him for being weak and then leaving.
