-->If so, I wonder why the Bible tell also " Dont' kill "

its a question of attitude. it also writes dont steal, lie or jump on your neighbours wife. kind of the jedi knight stuff just without the trash talk of yoda

the bible describes god as the essence of love your soul is part of, and it cant be if you refuse to be part of the whole picture. i cant be love if i act as hate algebra.

but this is getting kind of way too off topic.

if you want written permission god can still point to the bible Ex 20,4-6 and kick all our butts for generations.

it could get quite tricky to inprison god.
Because first of all you will have to proof that god killed those people or kills people in general.
