You say that you were particularly disturbed by the punishments prescribed for certain offences, presumably those for theft, murder and arson. As is explained in Note 42 on page 64 of the "Synopsis and Codification of the Kitáb-i-Aqdas", these punishments are intended for a future condition of society and will have to be supplemented and applied by the Universal House of Justice. The punishment for theft, for example, says that for the third offence a mark must be placed on the thief's forehead (nothing is said about branding), so that people will be warned of his proclivities. All details of how the mark is to be applied, how long it must be worn, on what conditions it may be removed, as well as the seriousness of various degrees of theft have been left by Bahá'u'lláh for the Universal House of Justice to decide when the law has to be applied. Similarly, only the fundamental principles of the punishments for murder and arson are given in the Kitáb-i-Aqdas. Wilful murder is to be punished either by capital punishment or life imprisonment.
