If there’s a way to get a response from one in a coma about whether or not they want to be on life support, it’ll help with the decision making of family members; maybe Elon Musk’s brain chip can help in the future.
If a coma patient is able to communicate to be taken off of life support, is it a form of suicide? If it is, I suppose the kammic consequences are not big since it’s an understandable circumstance?
