Its hard to lose someone, especially when you weren't on good terms with them when they die, but I feel like whatever may happen after you die, they probably can tell what you think of them really. What has been in your heart all this time, rather than just what you had been feeling towards them during rough patch lately. People in the midst of a bad situation themselves really have too much going on in their heads solviing their day to day problems that they don't always have time to care or solve why you weren't on good terms with them. Like, they still want to have your friendship but are willing to do things to hurt you in the wake of it because they don't see other solutions to their problems at the time. So, in that light, the person can probably reason with themselves and see that it would be understanable you'd be pissed about their actions, what did they expect, and all in all, still know you were someone who cared about them or else you'd have cut them out of your life long ago most likely.
I don't know if I'm explaining what I mean very well, but I hope you get it. Your post eulogized this guy well, there's a lot of feeling evoked by the way you paint the image of the mother coming over to borrow the money and finding him. Good luck
