Not to mention that she can barely effect two minds at the same time. She would need to make six minds see this. Look higher in the thread and you'll find my reasoning. But, as a condescenced version:

Cinder wanted to make Jaune and more importantly Ruby suffer. But Ruby was knocked out, so she focused on making Jaune suffer. Simply killing Weiss wouldn't be enough though, she wanted Jaune to feel the despair of knowing he could have saved her but failed too. So by having the illusion of Weiss die, she tortures Jaune so she can then force him to watch over and over, until she does it for real, with Jaune having no choice but to worry if the next one is the real one.

As for the mind thing, in Mercury's case that was on two minds for a prolonged period of time. This time though, we don't know if she really did it on anyone but Jaune. Note how while we see Nora, Ren, Yang, and Mercury react, their reaction seems more along the lines of shock than panic (Except Mercury's which is just smugness) And when we see Weiss again, no one is around her. Another shot showed Emerald was infront of the statue near Ruby, yet when Weiss is impaled and the statue is in the background, she is gone. For all we know, Only Jaune saw it and the others are reacting to his yell and wondering what the hell they're doing to him. Alternatively, maybe Emerald found a way to do it on more than one mind with less backlash.
