No one forced him to trade so much AUM. That's why a lot of funds close to new investors, stop taking new money altogether or even return some or all money to investors (even if they are performing well). A % return is a % return regardless of total AUM- if you don't have enough ideas to put that much money to work, or if your system isn't scalable to those amounts, then you shouldn't be trading with that much. Once you hit your levels of diminishing returns, it's time to slow down, not take on even more risk.
It's obvious he has a tremendous ego, which has probably contributed a great deal to his success but has also burned him multiple times. Who said you have to be the absolute best? Wouldn't most people be quite content being "only" in the top 1% of all traders, and not have to keep pressing until you're in the top .1%? Again, I'm sure he wouldn't have been as successful as he was without these traits, but there comes a point where it's no longer drive and determination, it's just plain reckless and irresponsible.
I just don't buy the "his investors demand such high levels of performance, that's why he took such extreme risks" argument. If he was uncomfortable taking such risks, he shouldn't have accepted the money to begin with. That's what I'd tell my personal friend, instead of looking at his career through rose colored glasses.
