The Good Snitch
Question
Dear Rabbi,
A friend asked my opinion about his starting a business relationship with someone I think is disingenuous and a conflict entrepreneur. My friend knows I stay away from that person, without any social media contact as well. But my friend is very enthusiastic to do a deal with him and asked me why I don't have contact with him.
If I were to be honest I would tell him, but it would be mostly negative and I don’t want to be a “snitch.” However, he keeps pressing me and I feel like I'm being dishonest by not telling him what I really think. He respects my opinion. How much can I say without it transgressing the Jewish laws and spirit that teach not speaking negatively against another person?
Thank you.
