I was actually saddened to hear of her death, Maggie did a lot of good too (Though granted it didn't make up for the bad...) She likely single handedly halted an aids epidemic in the UK, at the time needle use was high and it was being spread by dirty needles. (Not just heroin or other injectable highs, steroid users too) She introduced the needle exchange which has ultimately saved the NHS loads.
So RIP Maggie, can't fault you for standing by your word. Not many do that now.
