Listen, I really do believe that we shouldn't speak ill of the dead but...in this case I'm afraid that I'll have to make an exception:
I really can't feel (that) bad for people that had it all and then decided to throw it all away - drug addiction or not.
Couple that with the total absence of any kind of real talent (musical or not) and...yeah.
Crazy town was the definition of a 1 hit wonder and the fact that anything beyond that revolved almost exclusively around reality tv shows and the (unfortunately) usual "woe is me" doesn't really help in feeling any kind of sympathy towards this specific individual.
It'd be like saying that you're sorry about - say - Bam Margera when he'll (most probably) meet the same kind of fate.
This is not the same thing as truly gifted but troubled individuals that battled their own demons and finally succumbed to them like Chester from Linking Park, the ever amazing Chris Cornell or Robin Williams which on one hand you might be thinking "why?" on why the did it but at the same time you can really feel their pain and what they most probably were going through - depression really is a beast and it's the worst illness of the 21st century...
This guy...for better or for worse was just another druggie that had too much of what he was having, sorry for being blunt but I just can't feel any sympathy towards him.
