If my aunt hurts herself, would it be my fault?

My aunt lives with me. She has balancing problems, and she's fallen like 5 times In the past 2 months. Her brother was in the hospital yesterday because he had chest pains, and he has heart problems, and has had open heart surgery before. She asked me yesterday if I could go to the liquor star to get her some vodka, so she isn't so stressed. She had two shots, and she was shit faced. Later that night she got a call saying he was back home and fine. She got a call a couple of hours ago because he's in the hospital again with breathing problems, so she asked me again if I could go get some vodka for her. I did, because I just have a really hard time saying no, especially because her brother is probably going to pass away soon. I'm afraid she's gonna get shit faced again, and fall and get seriously injured. I realize I'm enabling her, but would it really be my fault if she can't hold her liquor and falls?
