A "scapegoat" is a term used to refer to an innocent person who is unjustly blamed for a wrongdoing and/or unjustly punished. The term originated from the Jewish custom of sacrificing a goat (representing the sins of the people) by driving it off into the wilderness as part of the ceremonies of Yom Kippur.
TL;DR, Don't Use it for commercial use since it's not my original character
