Is AUTHOR wrong in the post ? POST : So, the news came by that my dad got diagnosed with Alzheimer's disease...and my entire family wants me to take care of him. I am an abroad animation student at Canada, I am almost done with my studies and have been busting my ass to achieve my dream of producing animated films, I am already here and almost done, I am planning on getting a job and finally be my own man. But now I'm conflicted on this crossroads.

My dad spent his whole life taking care of his mom, who had the same disease, (she's lived with me for my entire life but she is constantly an asshole even in this condition). He has made it abundantly clear that he wants my sister and specifically me to follow in and take care of him when he is old, however...I don't want to let go of my dream, I am living the life I've always wanted and I am trully happy here. I wouldn't want to pass the blame on my sister who just started her studies or my old mom...

This is pushing my moral and ethic limits, what do you guys think?
