I would not be prone to deprive my loved one of food. If I abused, neglected or killed someone, it stands to reason I didn’t love them. It’s twisted to claim that brutally murdering someone is an act of love. Or that declaring someone’s life not worth living is an act of love. That is the ultimate selfishness.
Would you put an 85 year old parent with dementia, diagnosed with cancer thru chemo therapy? I wouldn't! IMO, that would be abusive and selfish!
If you consider that brutal murder, so be it. To me, it's humane.
