The emotiveness of an incident or claimed amnesia has no bearing on whether someone can be sent for trial. It is for the trial judge and/or jury to decide if a defendant is guilty of an offence. If a guilty verdict is delivered, then the judge may take into consideration all these factors before handing down a sentence. The law is rather dispassionate when it comes to dispensing justice for good reason.
Chronus suggests a horrific scenario that is so traumatic that few if any people could endure the consequences without blotting the incident from their brain. I would alternatively suggest that at 15° nose up and 225 knots, you will have no view of anything out the front except sky. Prior to that, you are too high and too far away to make out those sorts of details.
The AAIB report deals with the facts of the accident. The courts will deal with the facts of the accident. Any emotive issues will be considered only as they are relevant to the probable cause of the accident. So it is pointless speculating how, why, or if a case of amnesia might somehow absolve the pilot from the consequences of his actions that day. They won't as far as the law is concerned.
