A huge string in Iliad

" 1. The Greeks strongly believe in FATE or DESTINY, that is, nothing happens unless it is destined to be so. Does this mean that, in the Trojan War, the heroes' free and strong will to win is immaterial? Do you agree that the victories of the Trojans (in books 12 and 17) and the Greeks (in 13, 14, and 16) are all willed by the Gods? Explain your answer. Cite textual details."

Fate, Destiny, Constellation, The Stars... For me, it's just a string of lines positioned in a very complex way but still, ending up in one source. The question, for me, is just like a spider web. All connected to one source. The strings weren't there for just any purpose. It was designed for something to happen. Like the story from The Iliad, those strings had a purpose and one of those purpose is that someone or something needs to die. Either or Both of Spartan people, the Trojan People, the kingdom of Troy, heroes in the battle field... 

The Gods are so mighty and powerful that they control most of everything. Like the string of FATE. I strongly believe that they controlled the Fate of Troy. Like, from the chapter or book 15. Zeus wakes up and sees the havoc and chaos that Hera and Poseidon wreaked while he was dozed in his enchanted sleep. Zeus went wild because his plan of Hector dying only after Hector kills Patroclus. But, as a God, he still manages to go with the flow and fix the scratched string of fate. The plan of Patroclus dying was still continued.
