Maybe It was not a mistake because Wu saw Morro is very aggressive towards others so Wu afraid if Morro become green ninja he will use that power to rule Ninjago. Wu then uses normal golden katana and Morro didn't become green ninja. Maybe because Morro search for grave of first spinjitzu master and wants revenge. sorry for my english
