Though I doubt his kids have done 
anything to merit death as an apology,
رغم أنّي أشكّ أن أبناءهم قد اقترفوا
ما يتطلّب الموت تكفيراً عنه
Seine Kinder haben aber wohl nichts getan,
wofür sie sich selbst töten würden,
Pero los niños no hicieron nada
para suicidarse por ti.
Pero los niños no hicieron nada
para suicidarse por ti.
Mais les enfants n’ont aucun crime
sur la conscience,
Ma dubito che i suoi figli abbiano fatto qualcosa
per cui solo la morte possa redimerli,
Mas os filhos dele...
Но дети не сделали ничего, 
что бы заслуживало смерти.
