DEUT1236 "Do not despise your brother in your heart" (Leviticus 19:17). Thinking evil was considered transgression even when it was not accompanied by specific plans or intent to act out the thought. This is seen in the following passages: "When thou goest forth in the camp… then thou shall keep thee from every evil [davar ra, lit. [this verse, Ketubbot 46a], "words" or "thought"]. "And ye shall not go about after your own heart and after your own eyes, after which you used to go astray" (Numbers 15:39). "There are six things which the Lord hateth ... a heart that deviseth wicked thoughts" (Proverbs 6:16, 18).
