Everything that I've read about him indicates he was a rising star that willingly chose to withdraw from society, possibly due to mental illness. Far from the "vengeful deadbeat" that GP is claiming he was.
Note this isn't a diagnosis or an excuse (people often confuse explanations for excuses a lot), but it was a very interesting comparison that illuminated a lot of things. It provides a lot of potentials as to why for the steps in his life, opposed to the narratives which tend to be "prodigy turned evil" or "vengeful deadbeat" that are common in public narratives. I get why people like those narratives though, it's far less to process when we can paint someone in absolute ways.
