What gives these arseholes the right to kill?

An article from the Guardian details the murder of a Kurdish transgender woman by her brother, who may well get away with it.

It strikes me as perverse that it's acceptable to murder someone for being themselves but not for someone to live as they feel comfortable. This young woman was doing nothing to hurt anyone, so why kill her? The term honour killing is bizarre, it's a disgraceful killing and the disgrace is for the people who perpetrate and condone such murders. Shame on them.
