"Be strong", I whispered to my coffee.
Regarding the matter of people being killed by either Satan or God, just to play devil's advocate (heh), I was thinking about possible differences based on the theological implications.
For one, religion constantly drills into people the concept that "death" is not the end; it's merely a transformation from the physical world to the spiritual world. If this is true, then the act of God killing someone and then taking them into an Afterlife of paradise and happiness, then that may not necessarily be an evil act (if the theology is anything to go by).
It is said that God can create life, then take it away, then recreate it or resurrect it all over again. It is also said that God is the ultimate judge as to whether a soul goes to Heaven or Hell in the Afterlife. These are things that God can supposedly do, which Satan is unable to do.
Of course, this would also beg the question as to why religionists or God would consider life to be so darn important and meaningful that it would be considered such a horrific and abominable sin to take someone else's life. If death is merely a transformation from a limited biological existence to a spiritual Afterlife of paradise, then murderers are actually doing a favor for their victims (if the theology is anything to go by). Essentially, religion makes our own biological lives meaningless, so why would God or any believer be so concerned about "sin" in an existence which is utterly pointless and devoid of any real meaning?
A paradox to be sure.
