Is it permissible to kill the one who raped me and ruined my life, or should I be patient and seek reward from Allah?

We assure you that the boy who was raped before puberty bears no sin, as he was coerced and not yet an adult. As for the criminal aggressor, he is accountable for his actions and his discourse about his crime. He must be warned and intimidated, or reported to the authorities. It is not permissible to take his life, for the implementation of punishments (hudud) is the prerogative of the ruler. You must turn to Allah and supplicate frequently.
