Who to blame for Endikus death
In my opinion I would blame Gilgamesh for the death of Enkidu. Gilgamesh basically brought his life to risk and baited him. If Gilgamesh never brought the killing of Humbaba then the Gods wouldn't have to chose between Gilgamesh and Enkidu. In the text it says, "Has your strength left you, Enkidu?" Gilgamesh was asking Enkidu if he was brave and strong enough to face Humbaba, luring Enkidu to the battle and his death.
