Unintentional

Know that the prohibition against Rechilut [talebearing] applies even if the speaker does not intend to arouse ill will in the listener’s heart against the subject, and even if the speaker believes that the subject’s actions were right and just. For example, suppose that Shimon criticizes Reuven for something that Reuven said about him or did against him, and Reuven asserts that he was right in what he said, and that Yehuda even said the same thing. Even as a defense for his own actions, if Reuven has caused Shimon to feel hatred for Yehuda, Reuven’s statement is called talebearing.
