"Disgusting" is a human concept. And quite a subjective one at that. My vegetarian daughter thinks a steak is disgusting. I think it's delicious.

"Wants to kill us" is personification. Whatever it is that is killing you did not wake up this morning thinking, "today I am going to kill robthebold". It woke up thinking, "I am hungry". Then it found some source of nourishment. That the nourishment was you is just a bad luck. The thing eating you never even noticed that it was causing anyone any discomfort, any more than you would if you found a doughnut just lying about.
