No, the crucifix is not evil. It's impossible for an inanimate object to be evil. The idea is one of the teachings of the Jehovah's Witnesses. They're a cult that follow a mere man and is totally ignorant about Jesus Christ. Yet they have the arrogance to act like they know things that the rest of us don't.
Remind me to wear the mode of your death to mourn you on a necklace, I'm sure it would do a great honor to wear a rifle emblem to honor JKF, or perhaps a shotgun to honor Malcom X... Get over yourself dude, the crucifix is an insult and blasphemy against Christ... It's how he suffered and died for Christ's sake man!
