〜べきだ
should / ought to
〜べきだ expresses should / ought to — communicating the speaker's degree of certainty, judgment, or attitude about a statement. Modal expressions in Japanese range from strong conviction to vague possibility, and choosing the right one conveys important nuance about how sure you are.
This is an upper-intermediate pattern common in natural conversation and media like news, novels, and dramas.
