Yes he was, he planned on sneaking up on Danzo but then the whole summit was aware he infiltrated when BZ told the Kages, after Raikage went after him and Gaara was trying to stop him he had limited time to catch Danzo before he escaped hence why he went straight to where Danzo was.
And Sasuke wouldn't be in that position if White Zetsu didn't snitch on his infiltration in the first place
No, he wasn't forced. He decided to fight through the raikage. He was then saved by Gaara, willingly rushed into a room that had the other kages in it.
Almost died to Mei, then almost died to Onoki. Requiring himself to be saved by Obito. and had his chakra restored from white zetsu and Karin after Obito incapacitated his ass.
MS Sasuke is literally blinded by his own rage and desires.
Someone who was smart would have simply left and waiting for Danzo to leave rather than rush him in front of people who can end him. He was played like a fool the entire time.
His plan wasn't even his plan. It was Obito's.
