"God is all powerful, loving, and just."
He's none of those things according to your Babble. Well, he is but another part, often in the same fucking book, directly contradicts that claim.
"satan, on the other hand, is hateful and vengeful."
Then he and your buddy god should get along just fine.
"God allows bad things to happen so that it may bring people to Him and to work for His plan."
Then your god is a cosmic prick unworthy of mention, let alone worship.
"satan plans bad things to try to make people draw away and hate God."
I thought bad things happened because god lets them. Now you're saying they're Satan's fault...
"satan loves seeing people hate and be depressed and sad. God doesn't like to see us be hateful, depressed, and sad"
Are you absolutely sure that Satan and god aren't just two personalities of the same entity? They act an awful lot alike. Maybe it's like Clark Kent and Superman. Either that or your god is just mentally ill...
