what do you call a person who call out what there are doing wrong, like they tell on their self

Answer 1

A person who calls out their own wrongdoings or admits to their mistakes is often referred to as being "self-aware" or "self-reflective." In more informal terms, you might say they are being "honest" or "accountable." If they actively disclose their misbehavior to others, you might call them a "whistleblower" in certain contexts, although that term usually applies when someone exposes wrongdoing within a larger organization rather than personal admission.
