Wikipedia
Blame is the act of censuring, holding responsible, making negative statements about an individual or group that their action or actions are socially or morally irresponsible, the opposite of praise. When someone is morally responsible for doing something wrong their action is blameworthy. By contrast, when someone is morally responsible for doing something right, we may say that his or her action is praiseworthy.
