To accomplish something is to get it done. People usually accomplish things that are sources of pride — like goals or records. But people accomplish immoral acts as well — like scandals or cons.
The verb accomplish also means to bring about or put into effect. The CEO stood before the employees and outlined all she expected to be accomplished in the next year. She ended her speech by saying, "If we are to accomplish this, we must all work together — and work hard — but the rewards if we succeed will be great both for the company and for those that work here. Thank you for your efforts!"
