Rather than purchasing the meds that could save the life of my mother-in-law, I'm thinking of sacrificing her.
Why would you ever say such a horrific thing? Do you want her to suffer?
Yes, I do.
Sacrificing the life of your mother-in-law by not giving her medication is extremely disturbing. You should make sure you're there for your mother-in-law and make sure she gets the meds that she needs. Not giving her her medication will result in you being responsible for her death and you may be in legal trouble for it.
I will not change my mind.
Be if the family your born into, married into, or just someone you know, declining medication when you are able is wrong and sacrificing their lives is dark. It's okay to not love everyone, but it's important to care and do good, always.
