Taking of life being the operative phrase, I find no moral or ethical difference between the two. Coming from someone who believes they are created in G-d's image is truly sad. Most people find it unjust as well.
Pray tell what is this date? And don't weasel out with the oft-stated Christian talking point <paraphrase> "None may know the time and day of his return" crap.
God created Satan knowing full well what Satan would do and chose to ignore it.
Face it, you worship an unloving and unjust deity. I know that doesn't concern you and yet again, that is truly sad!
Matt 25:13 tells us we won't know the "day and hour", after Jesus used a parable.
Secondly, I nor any serious Christian cares about what you think about the God we worship as your opinion is one of perhaps thousands.
You don't have to worship him/it anyway. Move on to something that matters.
