ahhhh man! such a hard one, i for one cannot say anything cz wa2ta on7att bl amr l we2e3 of taking away someone's life i can't say now shou ba3mol!
There is this feeling of frustration that u get when u read his story, this feeling of him having lived like this for 7 yrs and still cannot find it in him to adapt. Especially that he was "3ayyish" abel, so it's just VERY frustrating to stop and put urself (la sama7 alla) in his shoes
i would very much consider ending my life aswell cz this isn't living, this is only existing so that the ones who love u can still interact with ur lifeless body but active mind.
I mean it's kinda selfish to not kill him, if he could do it himself he would have done it already, w why do we not want to grant him this wish of relief? cz we want him around? for our pleasure? what about his own sake? can u imagine urself living in a chair all paralyzed after having tasted life in full motion?
I don't see why not granting him this wish except for meaningless Taboos we hold in religious matters, humanitarianly speaking - the guy, in such a frustrating half living half dead situation - should be granted his wish..
