I've been watching episode 80. And something I've just realised. Gaara can die very easily. Like, for the battles, usually you will see Kakashi or Gai killing baddies so easily. And I think Gaara can die the same way as well.
If Rock Lee is fast enough to land a hit on Gaara, can't Kakashi throw a kunai faster than rock Lee's punches?? If he can throw a kunai right at Gaara's face. That would kill him instantly.
I think thats why Gaara is like Naruto. Still has lots to learn though. But when they go kyuubi and let out big monsters, then it would be another level. So in theory, they shouldn't let Gaara go Badger but kill him outright like normal ninja's do.
Just a thought. POst away!
