Sending Scores

I’m sending my ACT scores to college. However, I’m also sending my SAT subject test scores and I have taken the SAT twice as an eighth grader and as a freshman. Do I still have to send my SAT scores from the past? (Right now I’m sending them to Yale, Harvard, Princeton, Northwestern, and a few others if that helps). If I do have to send in those scores, will it hurt my chances if I didn’t do so well?
