You can sort of make your own decisions...
http://en.wikipedia.org/wiki/Hanging
It gives you a list of countries that use hanging. Iran will make you sick, because the last people hanged were recent and also young teenagers: 2 boys experimenting with their sexuality or just homosexual and a young woman (I think she was between 14 and 16) not acting chaste. Hanged all three of them. Publicly.
