Well, it looks like the inclusion of 'bandits,' in the next few days, will get rid of that problem. From what I can tell, they will be NPC's who spawn much like creatures, and will attack you if you attack them. Though they will eventually start attacking you even when you don't attack them, apparently. However ,that stage will be farther along, and something to get us acclimated to the release of PvP coming in September.
And I'm pretty sure creatures will either be updated similarly in that update, or else they will be given those traits (attack, run away) in a later update. But creature code has apparently been worked on, as they are currently not spawning after that small creature reset.
How many blasters would a blaster blast if a blaster could blast blasters?
