“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..”
Yes. There is.
– The video in #7 explains that process.
– They ask the patient to visualize “playing tennis” if the answer is yes. If the answer is “no” the patient is asked to visualize walking to the kitchen. Different parts of the brain “light-up” in the brain scan for those two responses.
– Watch the video carefully.
“If a coma patient is able to communicate to be taken off of life support, is it a form of suicide?”
Yes. But I rather not get into kammic consequences. Those are complex issues.
