This is easy for me: David. Everywhere David goes, people die or are violated.
When I read the topic, I wasn't certain who I hated the most, but I immediately thought to myself that "David is claerly my FAVORITE!.
You have the horny old guy knocking up sweet looking Bathsheba, (not to mention knocking off her hubby), the census thing, and so it goes, YET -- David is considered on of Jehovah's most loyal "friends" and is blessed repeatedly by Jehovah.
David's example always gave me reassurance that I WAS OK -- NO MATTER WHAT "SIN" I HAD COMMITTED, I WASN'T AS BAD AS GOOD OLE KING DAVID.
