Are you going to just stand by and let someone in trouble suffer?

Almost always used in the pattern 見殺(みごろ)しにする (to abandon someone to their fate). Carries a strong moral accusation — it implies the person could have helped but chose not to.

Common patterns

The figurative use is common in political and social commentary, where 見殺(みごろ)し does not literally mean death but rather neglecting people in need.
