What are the central ideas of this soliloquy

Antony is so upset about Caesar's death that he can barely speak.

Antony predicts that the land will be bloodied by men fighting men.

Antony expects Caesar's ghost to seek retribution for the wrongs done.

Explanation:

Even though it seems that he sympathized with the conspirators, after he is left alone, Antony reveals his intentions to make the crowd attack the conspirators in bloody murder. In fact, destruction and blood will be such that Caesar might even emerge from hell accompanied by the goddess of discord.

I believe the correct answer is character vs. nature.
Tornado Alley refers to a place in America, where tornadoes quite frequently happen. So, if this character is going to win in a 'battle' against a location, it is a conflict with nature. It is not within himself, or with another character, or with the entire society, but rather with a place, which belongs in nature.
