I don't think Sasuke cares too much about his team; I think he's basically said that more than once. However, it wouldn't be convenient for him or Madara if they're caught. Unless Madara reveals his big plan now; then it wouldn't matter. And the DEATH BOX was indeed cool.

And yea, i was actually happy to see a diverse village in Naruto, no matter who the leader is. And yea, Raikage is seemingly dense, but he is damn strong, and probably ther is more to him than meets the eye. I mean, they had 2 tailed beats containers, so they must be doing something right.
