Let's take your bolded words above, and look at a piece of caselaw:
If the jury determines that the defendant had not believed that he had needed to employ deadly physical force to repeal the victim's attack, the jury's inquiry ends, and the defendant's self-defense claim must fail.
If, however, the jury determines that the defendant in fact had believed that the use of deadly force was necessary, the jury must make a further determination as to whether that belief was reasonable, from the perspective of a reasonable person in the defendant's circumstances. State v. Miller, supra, 36 Conn.App. at 512, 651 A.2d 1318; State v. Williams, supra, 25 Conn.App. at 464, 466, 595 A.2d 895.
Note how you are saying similar things to the judge.
The the further in time from the actual combat, the more evaluation has to be undertaken, but as you approach the incident, and as options such as distance and cover are removed, the analysis narrows to the fundamental issues: Do I have to act to prevent injury to myself?
If you are wondering that and have time sufficient to ponder it...well, you tell me.
I'm not going to say "if x happens, go for it" because to me, that's a cheap way out of a discussion.
I'm not going to give an answer because I don't feel the question needs to have an answer given.
It has a method of finding an answer which isapplicable to the question presented, and to other situations that people can use for themselves to find the answer from the facts presented.
Once you do that, the questions become much more managable.
