I'm responsible for everything
that's happened so far.
أنا مسؤولةٌ عن كلّ ما حدث حتّى الآن
Alles, was bis jetzt geschehen ist,
hab ich zu verantworten.
Yo lo hice todo.
Yo lo hice todo.
C’est moi qui ai commis
tous ces crimes.
Sono stata io a fare tutto quanto.
Eu sou a responsável por tudo
 que aconteceu até agora.
