Metamorphoses - Erysichthon scene QUESTIONS

1. Erysichthon cut down the tree to make wood that would serve useful to him.  Erysichthon: "We need the wood, cut it down".
2. "Get off me, you, pious son of a bitch!" I think piety is relating to religious devotion.    Erysichthon insults the man by laughing at his religiousness.  
3. This term relates to Erysichthon, because he "scorned the gods and declined to sacrifice on their altars or do them honor. Nothing was sacred to him he only looked for the usefulness of things." 
He even makes fun of the man saving the sacred tree for his foolish religiousness ("pious son of a bitch!")  
4. The boy and Erysichthon are similar, because they destroy things to make them useful for them.  In this case, they both cut down a tree for their own interests (Erysichthon for wood and the boy to build many things).  Erysichthon and the boy are selfish, because they don't care about the tree or the fact that they are destroying something important.  They only care about the tree providing them with the materials they need to execute their plans.  

5. I can connect this to the time where Siddhartha almost committed suicide. 
"Siddhartha reached the long river in the wood, the same river across which a ferryman had once taken him when he was still a young man and had come from Gotama's town.  He stopped at this river and stood hesitatingly on the bank.  Fatigue and hunger had weakened him.  Why should he go any further, where, and for what purpose? There was no more purpose; there was nothing more than a deep, painful longing to shake off this whole confused dream, to spit out this steal wine, to make an end of this bitter, painful life."

At the end of the scene, Erysichthon finishes himself by eating his body parts to satiate his hunger.  Siddhartha decides to finish himself too at one point, because like Erysichthon, he can't withstand the hunger and exhaustion of his spiritual quest.
