Who else is mad that zabuza,haku,and kimmaro is died so early in the naruto show?

I think kimmaro would have played an important role in kabutomaru plot he doesnt even have a bodyguard like every great bad guy has someone who will die for them kimmaro would have been perfect but they wanted juggo to go with sasuke so they had to kill kimmaro but haku was the **** and if he was stronger than a s-rank crimnal zabuza he didnt even show his true powers vs sasuke and naruto they would have been important if they had got away from getting killed and returned when sasuke wasnt in the group in shippuden and had a rematch but they wanted kabuto to bring them back to life so they had to die im really getting tired of the naruto show for real
