twister found the punishment. Would it be strong enough to carry theur body upside down? 
I dint get you. Burning them alive or stoning them to death is a decent punishment but I am not aware of the law in that girl's country. The criminals usually don't get a death sentence for rape.
For raping, in countries which claim to follow Islamic rules, they will get a death sentence, obviously, stone to death.
I don't like burning them nor a living being alive though.
This may be splitting hairs at this point, but what really is the difference between burning somebody to death and stoning them to death? Is it just a personal preference, or are you taking something else into account, because I consider them both barbaric forms of punishment.
Both are painful. However, I prefer stoned to death. Personal preference.
