He's been ranting and raving all day about how it's her own fault and "she doesn't deserve the well wishes".
The public outpour will always be present in this day and age when someone famous passes. It may not be liked by some (I find the RIP.... Wishes whoever they are concerning a bit odd on a public forum like FB myself) but bloody hell they are aimed at the family.
Whichever way you look at it the circumstances are absolutely devastating. She clearly suffered from a serious addiction that she couldn't overcome. It's sad, I feel sorry for everyone involved. Do some people really have that little compassion that they can't see that even though it was an overdose the poor woman (along with millions of others) clearly suffered a lot in her personal life?
