Your god told me to kill you

This was taken from a serial killer's diary, which detailed his victims.

Your god told me to kill you as a sacrifice to them.
Your god is a liar and didn't care that I kill you, in fact, he laughed at the idea.
Your god told me not to kill you or anything at all. I wasn't even allowed to kill a bug in my house.
Your god told me to kill you to help the advancement of humanity, so I killed you and yours and gave your stuff to a charity. It's not like you did anything good for humanity anyways.
I was a god in your sight, so I took you, yours, and your stuff as your tribute to me. It's not like anybody is going punish me because there are no real gods.
I didn't know what your god wanted, so I killed you and yours and took your stuff to satisfy my needs.
Your god told me it was better than you didn't live because you were nothing but a defect.
Your god told me to kill you because you were a detriment to our society.
Your god told me not to kill you unless you become a real threat to others, so I'll wait.
Your god told me the same thing as the previous one though he thought you were stiffed necked.
Your god told me similar things but you are zealous, so I killed you before you killed or enslaved me.

Throughout all this, I've learned how right killing could be in the right situations. Some people's religions will allow them to kill more than they think. For me, it's right to kill this serial killer, right now.
