I would like to mention something else . A person does not have to act like a a**hole to be evil. Example the serial killer Ted Bundy was by all accounts a nice looking well mannered great guy to be around. In fact, he used his natural charm to lure his victims.
Now, for just one Watchtower example: A brother we know is easy going, funny, hospitable, loves people. He love to travel and entertain. he takes intrest in kids and frequently has get togethers at his house. He's handsome and comfortable in his own skin but doesn't mind making fun of himself. If we were stranded on a desert island HE's the guy we'd pick to join us. EXCEPT.......
Just one pesky problem though. He's a certified pedophile. The twist is, he and his wife filmed the heinous acts with the children and sold the porn for BIG BUCKS. Right before his criminal trial, the man he had hired to perform the sex acts "committed suicide". (yeah right) Without the starr witness, he got off. He soon moved to a different town and lo and behold, his wife, the professional photographer, mysteriously died of an "Asthma attack".(yeah right)
Nice guys aren't always nice. Sometimes they do evil things.
