Endermen are harmless until you provoke them they do not like eye contact, they remind me of a similar people, and that would be us autism kids we dont like eye contact or really lots of people and sounds at once. Endermen dont like weapons you dont see them having one or two and they especially dont like it when they are taken advantage of for their "Heads" its disrespectful to them they didnt do anything wrong to deserve this and dont tell me they attack you and you want revenge you probably provoked them first so.. yeah Endermen should NOT be killed take my word for you a beg you!
Kind of agree with this but an enderman is just a line of code, multiple lines of code, a script using java, it's kind of easy to script, and you can't tell people to not kill them. It's a natural things that occur, things die/killed, if people/humans don't eat, then we will die. But in minecraft, endermen dont drop food, so fair point.
