When translating "be" into Japanese, you must choose carefully between 役に立つ and 悲しむ. In Japanese, 役に立つ (やくにたつ (yaku ni tatsu)) is typically associated with "to be useful, to be helpful" (Syllabus Level: N4) and represents A set phrase meaning to be useful or helpful for someone or something. It describes the utility of an object, skill, or person. Often followed by the particle に. On the other hand, 悲しむ (かなしむ (kanashimu)) maps to "to be sad, to grieve, to mourn" (Syllabus Level: N4) and represents A verb expressing the feeling of sadness or an action of grieving..
