One being 'in-fear-for-their-life' can be interpreted in many ways, but the point being in a viable self-defense situation, there must also be 'mode' (example, a weapon present) and 'opportunity' or 'intent' which can include things such as proximity, 'visual-intent' (such as weapon raised or held in a an aggressive or threatening manner), etc.
On the flip-side, it may not be 'fear' that is the issue, but rather the visible-intent of the aggressor that justifies the response.
You are exactly right! I know there's a lot of posts to read here, but that's what I have been saying through out this thread.
However, if people don't want to take my word for it, with just a little time working their google-fu people will see what you and I are saying is pretty standard in the United States. The verbiage may change slightly depending on the AO, but the point is the same. For instance, some use jeopardy instead of intent, or capability instead of ability. However the it's the same three prong test.
Here's just a few links that took about 5 minutes to find discussing this topic.
