Yes, it is bad in large quantities over an extended period of time. Is that all it takes to be evil? If so almost everything qualifies.

Not only in large quantities, plus it is addictive (sugar). Note that they started out with cocaine, back in the day. Sure, different times, but still...

I don't want to argue about the healthiness of coke, though. If you want to drink it, by all means, go ahead. It is your life, not mine.
