I feel like waiting until someone has died to talk shit about them is a pretty cowardly thing to do myself. Even if you didn't like someone, death is something we all experience in our lives and we can all sympathise to some degree. Also criticising someone who can't respond to it or change because of it is futile and doesn't help anything at a time when people don't need extra shit on their plate.
I personally found I didn't like TB much outside his work, but it's too fucking soon to die at 33 and I feel bad for him and his family that he has.
