I do not trust anyone. I keep my head on a swivel because everywhere I look I see evil. Collect information perceptible and judge it based on your best assessment. Know you will be wrong to the degree your lack of wisdom and knowledge prevent you from being right. That lack of capability to perceive factual reality is endemic and unavoidable to humanity.
All we can do is our best, just like the rest. I am confident your best judgment is appropriate to you.
