LEV376 We are forbidden to give harmful advice. We are forbidden to cause someone to sin. The Chinuch (232) writes that there are two basic aspects to this prohibition: a) You are forbidden to give someone harmful advice. A person who seeks advice is blind about the matter in question. An example of this transgression would be advising someone to sell his house only because you want it for yourself. b) You are forbidden to cause or aid someone to sin. For example, if a fellow Jew asks you to give him unkosher food, you are forbidden to do so. Blind in this sense refers to someone who is spiritually or morally blinded by passion or ignorance.
