The question is "is it possible to build a world where there will be no bad words!?"
Yes!? it's possible but for that we have to build a world without any kind of jealousy, dishonesty, unloyality in one word a world where there will be no existence of inhuman quality.Then we'll be able to have a world without any bad world. As bad words comes from frustration and jealously, anger, dishonesty causes frustration. So as long as we can't eradicate those inhuman qualities we won't be able to build a world without bad words.
