I´m just watching!
Anyway, let´s think of this:
You rule in Hell: so you rule jealous and envious and evil and ass-kisser people.
You serve in Heaven: a peaceful and delightful place with good and just human beings like you. People are happy and people are helpful.
That stated, let´s assume: On Heaven, you won´t have problems. On hell, it´s more than possible violence exists. So, you´re reigning there, but for how long? You know your servers may be planning an evil conspiratory plot to remove you of your place and "kill" you. Therefore, you´ll live with fear, hiding from people and ordering a "trustful" "friend" (for how long?) as a spokeperson.
I´ll stick with heaven!
