Like Cart said, Sidious wanted to die anyway, and he wasn't on a powerful DS nexus at that point like Vitiate was when he ran into a saber. I pointed that out in my post. Missing the point is the norm for you, so it's ok.
Pretending that Sidious planned for it to happen makes you at least consistent with your stupidity. And apparently now we hold it against Vitiate for being on the nexus that he himself, created. LOL.
And you're in no position to gauge anyone's grasp on context, especially when you're incredibly dumb.
Also don't worry about law school pumpkin, it's unlikely you'll get through college with a forest gump IQ.
He has sufficient precognition, sufficient tutaminis, and sufficient reflexes to stop anything he really wanted to stop. So he either didn't want to stop it or didn't care.
Stop rationalizing and prove it. Or you're wrong.
Look at what you created Gideon. We'd kill for at least one intelligent Sidious fanboy. Instead, you breaded an army of stupidity.
