I think some human beings are probably more to be feared than almost any other creature. (Boston bombings, 9/11, that building in TX several years ago)
Most 'other' creatures - as far as I know - don't go out of their way to cause massive harm to others - most of their 'attack' - if any - are one on one for self-preservation.
I still prefer snakes, spiders, tarantulas, etc. to stay away from me. (Or me away from them)
