O.k. Here it goes, with all the advice you have already gotten, my personal belief is that everyone gets a second chance. I know, fat people bring about heart conditions, smokers have lung conditions and so on. Sometimes the transplant is what is needed to "save" their life. I am not talking just physically, but emotionally as well. Who are we to deny that one last chance. Something comes to mind about throwing stones in a glass house.
Now, with that said, as stated above, counseling, and other major conditions need to be in place, and if this alcoholic comes back needing a new liver because he continues to drink, well no. You had your chance. Hope this helps. From the way I read your post it was asking personal opinions. Thanks. Texas
