There's no meaning in a world 
saved by sacrificing you!
!لا معنى في عالمٍ أُنقذ بالتضحية بك
¡No tiene sentido
salvar el mundo sacrificándote!
¡No tiene sentido
salvar el mundo sacrificándote!
Ça rime à rien de sauver le monde,
si c’est en te sacrifiant !
Un mondo salvato sacrificandoti non ha alcun senso!
Não há sentido em salvar 
o mundo se sacrificando!
Какой смысл спасать мир,
если надо жертвовать тобой!
