Im just reading about the demise of donna, such a waist really as i really liked her, now, after months of the planning and the deals hes going to burn his daughters inheritance ill gotten or not thats aprils money and was for her future its mental, im actually not going to watch as it just really is the most unrealistic part of the whole story,

even if he didnt want the ill gotten money, donate it to the cancer charity or something, but burning it! crazy

Maybe you shouldn't judge until you know the whole story and remember that Marlon is basically an honest person with no criminal tendencies and does what a lo of honest people who are a bit scared would do. Unlike Donna. He can't hand it in so he does the next best thing.
It's not April's money. It belongs to the people it was originally stolen from.
