Based on the minimal info on the DU OP, my WAG is that the co-worker had advanced diabetes and died of an infection that just would not heal (plus or minus diabetic neuropathy). Type 1 Diabetes is something one is born with, and Type 2 is caused by lack of knife-fork-and-spoon-control. Either way, Star Moron BootinUp is projecting his/her hatred onto an irrelevant object of hatred. As fatboy pointed out, OhBummer!Don'tCare would have been more relevant.
