If you don't experience pain, you 
people will repeat your same mistake.
.إن لم تختبر الألم، فستكرّرون نفس الأخطاء
Wenn du keinen Schmerz erfährst,

para que no cometan el mismo error.
Tenéis que conocer el dolor
para no cometer el mismo error.
Vous devez souffrir,
sans quoi vous répéterez vos erreurs !
Se non conoscete il dolore,
commetterete ancora le stesse colpe!
Se não souberem o que é dor,
vocês cometerão o mesmo erro.
Если вы не познаете боль,
то продолжите повторять ошибки!
