I no longer have all that compassion and generosity I had as a bright-eyed newb.

You will have showed twice the compassion that was required and if she can either find someone to assist her or learn the hard lesson, maybe it will change her direction.Side note, can remember some tough times my Mom and I went through and in my late teens early twenties I went through, did not take handouts and learned to buckle down, made me the man I am today! 

-People need to eat, and not all of us have the skills and moral compass to go into hoity-toity professions like payday lending.

I just needed to learn how to close the deal ;p  So take everything as a stepping stone to the next, There is no driving directions, only a map and a compass in this game ;p you have to chart your own route

I would suggest taking it to the local news channel for a "compassion" segment.

To excuse oneself from having compassion, empathy, integrity, honor, VIRTUE.From all you've ever shared, I know you know exactly what I am talking about in this culture.

Further, with large corporations going into the rental business, one runs the risk of become faceless and lacking in compassion from a perception point of view.

When in small claims court the Judge may listen to the hardships you've been through but has to rule by the law Not emotions.This would be a good time to appeal to the landlord and see if they feel compassion for you.

Second thing is...a little bit of compassion can go a long way. 

For someone who lacks a moral compass and has no qualms about "sticking it to others" for their own benefit, hiding the fact that a loan's due-on-sale clause has been triggered is no big deal.
