dude, if you havnt read notches blog then you are probably like 3 weeks late. the endermen will stop moving as you look at them with the reticle directly on them. meaning they are passive until you look at them
If you look away though they will run up to you and kill you,

1st they arnt like creepers cause they dont explode nor chase you.

2nd herobrine is still not approved to be real. so dont even think of adding herobrine as your options.

Thank you.

warning: endermen they will find, they will hunt you down, if you see one dont look in the eyes,
it will find you

there like herobrine they sneek up on you then attack like a creeper but no exploding
