An Argument Against Pleasing the Gods

It is said that gods are a way for humans to keep a moral conscience. In one blog, it was said that the authors of Gilgamesh cared only about pleasing the gods. I must disagree with this point of view.
If the authors of Gilgamesh only cared about not incurring the gods wrath, why did they provide several instances where the gods fury is fully brought upon Gilgamesh and Enkidu? When Enkidu and Gilgamesh go to kill Humbaba, they realize he is the guardian and protector of the cedar forest, a forest created by Shamash, an all powerful god. Thus, the protector of this forest is dear to Shamash. So when Enkidu tells Gilgamesh to kill this monster, he knows it will infuriate at least one of the gods. So why would Enkidu tell his dear companion to do this, knowing it will make the gods angry? Why would Gilgamesh follow through with it? They did it because they wanted to leave a legend, even if that meant enraging the gods.
If Gilgamesh had only wanted to appease the gods, would he have turned Ishtar away? Would he have said the nasty things he said to her, if he did not want to make her angry? No, if he had wanted to keep her anger away from him, he would have gone to her bed, no matter what she had done to her past lover’s. He would have complimented her and told her how beautiful and kind she was. He would not have pointed out how she struck every past lover, broke wings, and turned them into blind moles.
This story is not about the gods, whether it is soothing them, or angering them. It is about a man who risked everything to find who he was.
