The Uchiha are weaklings without the Sharingan. Do you honestly believe a single 18 year old kid could slaughter his entire clan without having some sort of advantage? That's why he killed Shuhei first, to get the Mangekyo, which enabled him to single-handedly wipe out his clan. The whole reason that the Senju probably didn't kill the clan was because of the Sharingan; they knew its power and kept the Uchihas around so they had some sort of advantage in the wars.

Madara not using his Sharingan is like Hinata or Neji not using Byakugan or Naruto not using Shadow Clones. It's their signature technique for a reason.
