After meeting with the Edo Tensei Itachi, yes, Sasuke wanted to meet with the first four Hokage in order to resolve his sudden uncertainty. When he found out that his life, up until now, had been nothing more than a crock of Uchiha nonsense (thank you for that, Hashirama), Sasuke decided that the village should be preserved, but that they old system (tailed beasts and whatnot) needed to be destroyed.

During his meeting with the Hokage, however, he told them that if they didn't tell him what he wanted to know, he'd demolish the village and its people, which is what caused Tobirama to attack (and unfortunately, Hashirama intervened).
