He couldn't give up smoking, it was just too hard. He had stress to deal with and the cigarettes made it easier.
His wife (my sister) has it harder now. She is watching him, her 55 year old husband die a slow death. She has plenty of stress and lots of heart ache. Cigarettes are not going to make this pain go away.
I know it is wrong to hate, especially to hate a dying man but I can't help it. He could have been stronger. He could have fought this addiction. He could have had a long life with the woman who loves him. I hate him for what he has done to his wife, his children and his grandchildren.
