Forgive me, for I struggle to be brief.
The central theme of AM's life is greed. He appears to be fine with draining people who have so little in the way of resources socially, physically, or financially if it benefits him in any small way.
Relationships are the currency of the poor. If your truck breaks down, you don't call a tow truck, you call a friend or neighbor to help you. If there is a tragedy, people rally around you and bring you food, or donate $ to help you out. Affluent people pay for all of the services that are typically provided by the friends and family of the poor. People living in poverty protect their relationships fiercely, and will give up many of their limited worldly items and $ to help a friend out.
AM can take advantage of the people around him because they are playing with two different sets of values and rules, and he seems to straddle the worlds of the advantaged and the disadvantaged. The poor people around him are operating under the assumption that you help a fella out whenever you can. He is operating under the principle that you always take the biggest slice of the cake that you can secure. It is a recipe for imbalance and predation.
AM loves to sidle up to someone with the 'ol "Hey Bo, can you do me a favor?" You can hear him working on Buster in this way in the jail calls. AM uses the kindness of others to get them to do what he wants, and he is not encumbered by the principles of fairness. He makes unreasonable requests, but he does it the folksy tone of the poor, and people feel obligated to help him out. He has really mastered how to get people to feel sorry for him in circumstances where he has no business requesting anything, and as I have said before, this is how he operates as a predator. His lies are almost always about garnering sympathy, and he knows how to tap the sympathy vein for $ and pity.
Anyone entering into a relationship with AM needs to ask themself, where am I being punctured, and what is he draining from me?
Relationships are his weapon. Does that make sense?
