Actually, yes, that is why a defense attorney doesn’t ask certain questions. He can’t give client/lawyer confidential information. However, if he comes into physical evidence, he is required to disclose it as an agent of the court.
spaklite2: “Is the defense required to share damning evidence?”

Correct answer - no, the defence is under no obligation to “share damning information”, it is the prosecution’s responsibility to make their own case.
The reason why a defence attorney does not ask certain questions is to avoid knowingly suborning perjury.
