What ' s the point then ! ? Why not just let him go ? Sorry if this sounds insensitive , but my family went through a similar situation where a distant older family member was in a coma due to an accident and when she came out she was . well . I don ' t know how to put it but she wasn ' t human anymore . She couldn ' t breath on her own and had to be on life support all the time . She couldn ' t eat , she couldn ' t speak or even communicate in any way . But she was alive or at least not dead . She stayed like that for months . A daily life of non existence and who knows the amount of physicalmental suffering she ' s been going through . Not to mention the huge costs her sons had to endure to the point of being in debt . When she finally died , it was so surreal to see the relieve on the faces of everyone involved . I only visited her once mainly cuz I didn ' t really know her that well , but I could swear with all that ' s holy and divine the look in her eyes when we briefly had a moment of eye contact was that of someone who gave up and is begging for mercy . I will never ever forget that look of defeat .
