Well genjutsu is not actually actually happening. it's a illusion happening in the mind right?

You still haven't explained why a normal genjutsu wouldn't have been enough.

Genjutsu, in my opinion can't really make the person die. its obviously not that powerful. Itachi's tsukuyomi was famous for it's time manipulation which causes brain damage which only certain amount of people survive from. It's a one shot genjutsu, it's purpose is to kill the person by expanding time in the victim's mind. It's time manipulation is what causes it's victims to have brain damage not the torture.

Shouldn't Sakura die then? by the chidori genjutsu of Sasuke's? Or Danzo die from the amaterasu genjutsu.Or Sasuke mostly being half blind since his eyes wad taken from him. so shouldn't his brain think he's half blind?And shouldn't Kakashi have died since his body would have already lost alot of blood from the stabbing and instead was able to suvive it for a week till the sannin could heal him.

Basically genjutsu still has a limit. Normal genjutsu users like Uchihas use genjutsu and then approach to kill the person(eg: Madara using genjutsu on Raikage and then trying to kill him) and Sage mode Jiraya using genjutsu on the paind and then killing them.

The curse mark transformation is something Sasuke uses when he is using his full power so in the genjutsu, where he is completely trying to overpower Itachi,he was able to break through it. The CM wasn't visible after the genjutsu to show that it never happened and the zetsus never talked about the CM and instead just praised about Sasuke's eye power.

Experiencing Tsukuyomi's is what needed to cause brain damage. That is why a sharingan user like Izumi died from experiencing it with 71 year time.

The first time Itachi wanted Sasuke to be filled with hate and revenge and grief from his parent's death ( a key ingredient to the said believed way of awakening MS) So to gain the said eye.

The second time of the genjutsu was to show him the reason for why he is taking his eye, I mean he can't just go with "hey you have nice eyes! I want them!".so he had to show the reason for why he is taking those eyes.

And yet he prepared Shisui's eye to totally change him after he expects Sasuke to takes his own eyes.

@Kakashi. Why not? Tsukuyomi was a MS jutsu. it wasn't through Itachi's own genjutsu skill but through his MS. So in my opinion after Six Tomoe Rinnegen Sasuke capturing all the tailed beast at once with just a glance proved that his genjutsu prowress has surpassed Itachi's genjutsu skills. And don't take Danzo's comments about Sasuke's genjutsu skills. he was clearly being fooled by him lol. And I hope you rememeber C's word of Sasuke's genjutsu skills saying people like him are rare, so please don't take Danzo words when he was being tricked to compare his genjutsu skills.
