After his untimely death, waking up back in Axis is disorienting. Concepts previously censored from his very memory come streaming back in.
Also, his plan of "dying heroically" to guarantee he didn't get sent to a lower plane but still escape his obligations has some deeply obvious holes now that he actually has longer than half a round to think about it. If it was deemed "breaking his promises" he could have lost his Law. If it was deemed "suicidal" it could have counted towards Evil. He can't remember the court precedent on how previous life actions vs. after life actions vs. latest life actions count for long deceased people that have been resurrected. But even if he had time to think before his little "heroic" suicide charge and had read enough trial transcripts to know the relevant case law... in hindsight it seems the censorship of his memory would have likely blurred out key details.
