Dayz epoch does killing UN ai lower humanity?

[lynchk28 0]

 I've played my share of dayz but i'm pretty new to epoch. The other day I made it to the trader city at klen and started looking around. While I was there i noticed that other players were accidentally running over the ai guards but the guards were not responding. Being a noob (and a bit of an asshole) i decided to farm the ai by running them over with a car then taking their guns and selling them. They never attacked me nor did my humanity go down, but when i logged in the next day my humanity was at -26000 and they instantly started shooting me. So, is it that running over these ai lowered my humanity (it just took effect later) or is it a bug or something? and also will restoring my humanity stop them from shooting or will they always shoot me after what I did? I really dont want to have to abandon this server. Thanks so much in advance  :)

If you kill survivors or military AI, your humanity will go down. However if you kill bandit AI your humanity will go up. 

This also applies to normal DayZ servers with AI.
