No one has suggested you would just execute a person on sight while they are under the influence.
In these situations there are interviews, evaluations and waiting periods to ensure the person is 'of sound mind' before proceeding.
So with that cleared up, I'll repeat my question.
Why should you get to be the arbiter of if someone else is allowed to die?
It's nothing so complicated as all that.
It's as simple as any possible solution to the issue is to Israels disadvantage, so they work to maintain the status quo.
