With whom does the “i” of the chorus identify as it vows to keep an open mind about oedipus until there is “certain proof” of his guilt?

In the Oedipus the King, in some cases hilariously inhumane or whimsical, now and then keen, now and again sensational, the Chorus responds to the occasion in front of an audience. The Chorus' responses can be lessons in how the gathering of people ought to decipher what it is seeing, or how it ought not to translate what it is seeing.

Because it was a trading route.
