Buying off Negative Qualities Options

[yesferatu]

Hey guys,

I'm researching some negative qualities and I'm trying to figure out how I'll eventually get rid of them.
I understand how you would buy off an addiction or skill limit or something, what about stuff like debt?

If you took the Debt negative quality and eventually paid it back (in cash) - do you still need to spend the karma to get rid of it?
What about Enemies - if you kill them...do you need to buy the quality off in karma too?
What about like Hung Out to dry? Do you actually need to buy that off - or do you just need to make new contacts?

I couldn't figure out why you'd need to basically pay double to get rid of those.
I'm still not sure.
