My God this article is full of stupid, awful arguments. Seriously some sort of agenda behind it. I hate the death penalty. However, if they're going to do it anyway, nitrogen hypoxia is definitely the most humane method.
in my opinion - and I'm just some guy - there is no humane way to kill anyone who doesn't want to die. It is a contradiction in terms. Therefore regardless of the method, it is simply "not humane."
This is why punitive justice is pointless. We need to rehabilitate criminals, not just warehouse them. Obviously some criminals are harder to rehabilitate and reintroduce into society, but the vast majority of these people are not sociopaths
