will answer, will respond, will answer for it, will be held accountable
Собственной кровью ответят!
They'll pay in their own blood!
— Бункер (2004)
Пусть ответят.
Let them answer.
Но предатели ответят.
But the traitors will pay for it.
Те, кто сверху, не ответят.
Those at the top won't answer.
— Платформа (2019)
Но не парься, они за это ответят.
But don't worry, they'll pay for it.
— 1+1 (2011)
Пусть они ответят.
