Before I found this site I strongly beleived there was no God. Now, I realise it's scientifically impossible to prove God doesn't exist so I am sitting of the fence. I hope that makes me qualified to answer...
A "thing" is good if it benefits someone without harming another - God's command is irrelevant.
Are you posing the question "If God asked me to kill, does that mean it's OK?" (Although slightly off topic, that's how religious fanatics justify evil deeds.)
