A more thorough explanation:

Definition: Guiltless is an adjective that describes someone or something that is free from guilt or wrongdoing. It can also refer to someone who appears innocent or has the quality of innocence.

• He was found guiltless of the crime because there was no evidence against him.
• She had a guiltless conscience because she knew she had done nothing wrong.
• Even though he was accused of stealing, he had a guiltless expression on his face.

The first example shows how guiltless can be used to describe someone who has not committed a crime and is therefore free from guilt. The second example illustrates how guiltless can refer to someone's conscience or state of mind. The third example shows how guiltless can describe someone's appearance or demeanor, even if they are actually guilty.
