When no one was looking I replaced their smoke detector with a fake one
You know the fake one is not going to work, right?
What I want is to have the house burn down! Their heads are full of shit if anyone believes them! They are dumb jerks
That is not okay! You should not lie about the fact that you replaced the detector. You could really hurt them!
Do you think I give a shit? I want to see them burn.
You don't have positive feelings towards these people and that is fine, but do you really think that it's okay to knowingly put them in harm's way? If the house burns down and you are caught, you could be arrested.
