probably they dont understand the meaning of loneliness. put them in the actor's shoe and see what happen.

agree with the "blood into serum and test" thing, some people just dont get it, he know he is the cure coz he is not affected, he want to cure those who are affected by injecting his blood in them but it doesnt work. so he need to experiment! and test! and find different approach! and why test on rats? so you think its easy to catch a zombie everyday to test eh? some people. my goodness. cant help myself to be offended by their stupidity.
