What is prophetic about Creon remark that natures like yours chiefly torment themselves?

Creon's remark that "natures like yours chiefly torment themselves" is prophetic because it foreshadows the tragic events that will befall him. Creon is a proud and stubborn man, and his refusal to listen to the advice of others will lead to his downfall. He believes that he knows what is best for Thebes, and he is unwilling to consider any other options. This arrogance will eventually lead to his own destruction.

Creon's remark also foreshadows the fact that he will be the one who ultimately suffers the most from his actions. He will be the one who is left to mourn the deaths of his son, Haemon, and his wife, Eurydice. He will also be the one who is left to deal with the guilt of his own mistakes.

In the end, Creon's remark proves to be true. He is the one who is chiefly tormented by his own nature. He is the one who is left to suffer the consequences of his own actions.
