Both sentences are grammatically correct, but the preferred sentence structure in standard English is "You, he, and I are guilty."
In English, when listing multiple subjects in a sentence, the convention is to use the subjective pronouns in the following order: "I," "you," "he/she/it," "we," "you," and "they."
So, the correct order for listing the subjects in the sentence "You, he, and I are guilty" follows the standard English pronoun order. However, both sentences convey the same meaning, and the difference in word order does not affect the correctness of the sentence.
