First of all please show me the panels where Kimimaro called Orochimaru "Kami-Sama"... I must have completely missed those. He even questioned some things Oro said, like for example that there is no meaning in life. Thats nothing he would do if Orochimaru was god for him, because in that case his word would be absolute.
Being Naive?!, You are saying Kimi is naive... mistaking a man for a god is delusional, it surpasses naive and goes beyond it, way ,way , way beyond it and yes I can blame him for anything his freaking character does, regarthless if it's stereotypical because the character itself is made out of a stereotype (one of a character being enormously stupid... stupid enough to mistake a man for a god).
