>But you could have the least worst of the three worst evils.

No you couldn't. Dr. Bill is correct, a superlative is the end of the line. If something is not as bad, less horrible, less evil, or whatever, it is, by definition, not the worst. This one is so simple even I can get it. Something is either the worst, or it isn't. Or are you suggesting it's possible for someone to be a little bit dead?
