"what if someone with Mr Shaikh's aledged mental disorder travelled to a foreign country and raped or murdered someone, would people still say "poor man" and how sad it was?"
well we had a case not disimilar to that situation right here in the UK very recently. A man with a serious sleep disorder murdrered his wife in his sleep. The jury were told to either find him not guilty, or not guilty by reason of insanity.
They chose the first option, he walked "free"
Just like with someone with a MH issue there was no way of knowing before hand he would do that before hand, and it was because of his disorder that he killed her. No different imo than of any one with a MH issue who has commited no crime previously, but then as a result of the illness commits one.
On this case, well I'm against the death penalty in any circumstance, but also abide by the "when in rome" thing, ie you commit a crime in a country which has the death penalty and are caught then sadly you take what is given in that countries judicial system.
HOWEVER, in this case I don't think his mental health issue were take into account, and in any trial, anywhere in the world I believe all circumstances should be taken into account. No doubt the man I mentioned above in my post would have bee executed in China had he killed his wife there, as I have little faith that they would have looked at any of the medical evidence.
