Dammit man, pay attention to the context.<quoted text>
Yes. But he is not saying to accept killing for behavior. Do you see him saying that anywhere?
You talk about context, and you want to focus on one word?? You are an idiot.
I'll explain what he is saying for you. He is talking about the "link" between belief and behavior, and since we recognize the "link", and since the behavior resulting from certain beliefs is so horrendous, we need to consider killing for the belief, before the behavior occurs.
Put another way, beliefs make people do awful things, and understanding the link between believing things and doing awful things, we need to kill them first.
If you don't get it after this, you will never get it.
The sixth word is 'and'.
