I trust the superinvestor's original intension may be good but human can change when they are faced with greed and fear or their proudness. He may not be after wealth at all but fame. At his age and his account balance, I think he is after power and fame.
It is not unusual to see someone started with very good heart and turn into something else. This can happen between wife and husband, parents and children, brothers and sisters and best friends, I am sure you have heard a lots of real life stories when money is involved.
Everyone is deserved to be given chances to change.
I am sure he is also very brave to admit his mistakes and let's stop attacking him and let him continue to do his good work that help people (the right way), whether poor and rich will also be beneficial.

One of rare and good writing in i3. KC, salute you. My lousy article pale into insignificance by comparison. I really feel for the slaughtered one. May be God really work in mysterious way to stop him from doing such things further, unfortunately, the old man get the wrong message.
