I agree with orochi completely. Naruto would be even more childish if he couldn't see through the lies they were telling him, "oh okay its just animals i'll go back to my room". You can't expect him to be the perfect character, there's almost no route a mangaka can take now that wouldn't be "cliche" compared to one of the thousands of works out there
. He could sit inside, sip some tea, take out a pen and write out a plan, that would be cliche, he could ignore it til the war is over then come and rage after seeing all of the damage done/as in the pain arc, that would be cliche. He's doing what he's best at and thats who he is.
