This is not a threat. This is a fact.

Lawyers give their best advice based on what the client tells them. Based on what the “facts” are can significantly impact not only the outcome, but also the advice given.
Routinely, clients have denied certain conduct and based upon those assertion, advice is given. Then, the other side files a pleading alleging the very conduct. Many times I have called opposing counsel and asked that they provide the proof, as it may well change my advice.
When you lie to your lawyer it impacts your case. It impacts the advice given. It impacts the strategy of the case. It also impacts what your lawyer believes from you thereafter. AND, it can also impact the outcome of your case.
So, did you lie to your attorney about a material, critical part of your case? Did that lie effect the advice given and strategy used? Did that lie come back to bite you in the tail (and could have been minimized had you just told the truth)? So, think long and hard about lying to your attorney – – and don’t do it.
