I'm sure most people have wondered about it, yet the reputation that comes with killing someone is enough to discourage all desire of doing so. However, I agree with the fact that the best prey is a human being. By hunting your own kind, everything the hunter could've thought of could've been thought of by the prey as well.

^yeah but haven't you wondered what the killer feels
i am talking about someone with no remorse there has to be something they feel good or bad

Depends on the situation....dummy.
