Do you believe in assisted suicide without medical reason?

So for some context, this is a debate in my family at the moment.

My grandmother has been a widow for 15 years, her life was totally devoted to her husband. She’s an elderly lady now.

All her kids and grandkids have grown up. We love her very much, and all make time to see her and include her in our lives, but admittedly, this can be a burden and we feel guilty if we get too busy.

While she loves us very much also, she has mentioned before that she no longer has a purpose to live, she is no longer needed and doesn’t want to be a burden. It’s really sad, and we do our best for her but that’s how she feels.

She is in perfectly good health. Should she have the right to choose to end her life when she pleases, having total satisfaction with the age she’s reached and feels the earth has nothing left for her? Is it kinder to let someone have the right to die happily instead of waiting for ill health and to die without dignity?

I hate the thought of growing old waiting to die or become sick or be lonely.

Is it selfish to do to your family? Or is it selfish of the family to not allow her to fulfill her wish?

DISCLAIMER this obviously isn’t something we’re actually discussing doing. It’s purely hypothetical
