A person can be killed instantly through many different means.

As we know it, to be killed painlessly, is to be killed instantly.

If you instantly destroy a person's entire brain then they died without pain.

Yet the most effective ways of instantly destroying someone's entire brain are considered inhumane.

If instantly killing someone by smashing their head with a massive rock, or shooting them in the brain stem is inhumane, then there is no humane way to kill someone at all.

    Inert gas asphyxiation is considered as painless.

    Accordingly, the human subject detects little abnormal sensation as the oxygen level falls. This leads to asphyxiation (death from lack of oxygen) without the painful and traumatic feeling of suffocation (the hypercapnic alarm response, which in humans arises mostly from carbon dioxide levels rising), or the side effects of poisoning.
